We’ve linked videos in this series many times before, but it’s wuite a doozy this time. Final Fantasy is known to have a number of combat bugs. Critical Hit chances are determined by the index of the weapon in the weapon table, not the stat in that table; weapon special properties just don’t work, regardless of what the Nintendo Power Strategy Guide says; and more.

This isn’t just an explication of those bugs though, it goes through all of how basic (non-magic) combat works in the game, explaining the value of all the stats. That’s one of the things about RPGs: you’re told items are “+4 better,” but often those values don’t match up to what they’d mean in D&D, where a plus is usually either a one-point increase in damage, a 5% improvement on odds for something, or both. Final Fantasy’s attack roll turns out to be a 1-in-200 die, so, a mere +1 is negligible to attack odds.

They probably didn’t elaborate on what these numbers mean in the manual because, at the time, Square and Nintendo were keen to get players hooked on Final Fantasy and other JRPGs, and nothing would dissuade them from picking up the game than to be confronted with battle formulae in the manual. Looks too much like school work! But they could have at least mentioned something about relative chances?

If you really want to know what the numbers mean, the video is there waiting for you. You can just let your eyes glaze over during the math if you want. I won’t tell the teacher!

Famicom Galaxian, never released in the US until Namco Museum Archives Vol. 1, is a tiny program, even by Famicom/NES standards. It may be the smallest Famicom game; the ROM is only 16K large, taking up just half of the addressable cartridge space.

But even such a little program can hide secrets. Adrian found a multicart with an alternate version of Famicom Galaxian with rapid autofire, and that he preferred to play that than the official one.

And I don’t blame him! Galaxian nowadays, whether a port of the arcade original, is a slow and clunky thing to suffer through, but even back then there were some people who scratched their heads at its popularity. One of them was Craig Kubey, author of the classic-era arcade book The Winner’s Guide to Video Games, who called it the Worst Popular Game. But these problems evaporate if you can just hold down the button and annihilate the aliens, like you were playing Centipede.

Namco must have realized how much better the game would play with more shots, as they made your ship in Galaxian’s successor Galaga fire faster, and can have two shots on-screen at once. four with the double ship. Maybe as a result, Galaga is a lot more fun to play, even today.

Adrian got to wondering about that alternate version, called “Galaxians” in the pirate cart’s menu. He found a ROM image of it online and had a look at its code in Mesen’s code analysis tools and found the first thing the “classic” version of the game on the cart does is write a zero to a specific address in zero page. This, as it turns out, is to ensure a secret cheat is disabled. If a one is written there instead, it produces behavior exactly like the rapid-fire version, which in addition to being able to fire much more quickly recolors the logo on the title screen red.

Is this a disabled cheat function on the original cartridge? Maybe, but maybe not. Adrian found another version of the Galaxian ROM online that doesn’t have the cheat function, disabled or no. It’s unknown if this is an alternate official release, or the only official release. Maybe the version on the pirate cart was hacked to put the code in, or maybe it’s an obscure unreleased version, or else maybe it’s the Famicom Disk System version?

Geez, the mysteries abound concerning this sucky little game! Find out about it yourself here:

Human-readable numbers are tracked by computers in a number of different ways. Nowadays we basically just do a printf or some version of it, but on a 1 megahertz platform, optimization really matters. It’s easy to think of computers as being impossibly fast, but in truth speed only ever counts relative to the efficiency of the algorithm you use. Computers are fast, but they aren’t all that fast.

One of the big tradeoffs in processor design is, fewer complex instructions that do a lot but take a lot of cycles, and processor complexity, to execute, or many simple instructions, each doing little and being relatively simple, and not needing a complex processor design to implement.

The 6502 microprocessor generally follows the latter design philosophy. It made some important tradeoffs to keep costs down. For example, it doesn’t have hardware that can multiply arbitrary numbers together. It relies on the programmer, or else a library author, to use the instructions given to code their own multiplication algorithm, if they need one. The result is going to be slower, probably, that if the chip had the circuits to do this automatically in silicon, but it reduced the cost of the chip, basically allowing more to be made, or else increasing the profits for the manufacturer.

Personally I’m a fan of just storing the score as a series of digits that match up to their positions in the character set. Gain 1,000 points? Just bump the 1000s-place up by one, and if it goes past 9, subtract 10 and bump the 10,000s place. That’s a tried-and-true system that many games use, and works well if all you ever have to do is add numbers. Comparing values, like for detecting extra life award levels, make things slightly more complex, but not by much. There’s sometimes other factors involved though, and that may explain why Super Mario Bros. uses different systems for its counters, as explained by NESHacker.

I won’t keep you waiting for the link: here it is. And here is my grossly simplified summary, intended to inspire you to go to the original article, if you have the time, and get all the deets.

Guardic Gaiden, known in the US as The Guardian Legend, uses a weird trick to put its status bar at the bottom of the screen, instead of, as usually seen in an UNROM game, at the top. To create a fixed status window requires stopping whatever the processor is doing at a very precise time while the display is being drawn to the TV, and then changing some PPU registers to display the status.

More complex and versatile mappers, like the MMC family, have the ability to trigger interrupts at specific screen lines, but Guardic Gaiden/Guardian Legend doesn’t use an MMC. It doesn’t even have a raster line counter, so the game simply doesn’t know where on screen the raster beam is drawing.

There are still lots of games on the system that have status windows, even with MMC chips. The PPU has a built-in feature called Sprite 0 Hit, where the chip can signal when Sprite 0 (of the system’s 64 sprites) is being drawn on top of non-transparent background data. So what older games commonly do is put Sprite 0 in an unobtrusive place at the bottom of the status window at the top of the screen. When the Sprite 0 Hit register indicates a collision, the code knows it’s time to set up the PPU to display the main portion of the game screen.

There is a really big problem with this setup, though. Sprite 0 Hit doesn’t trigger an interrupt. It doesn’t stop the code to let it switch the graphics. It’s not even proper to say it “sends a signal.” It’s up to the code to check if Sprite 0 Hit has been triggered. If it has, then it’s time to set the scroll register to the right place, and maybe switch to the proper background tileset, and do whatever else needs to happen, and the code can then be off to run essential game logic, the actual game part of the game.

If it hasn’t… then, the code has to check again, and immediately. And if it hasn’t triggered then, to do it again. It has to literally check as quickly as it can, because if it delays in its check, the game screen might not get set up at the right moment, which will be perceptible as the bar straying down one extra line that one frame. Not the end of the world, but it looks glitchy. And this code will be running every frame, so if it strays down once, it might do it again, which is a more perceptible glitchiness.

Sprite 0 is set to trigger its hit at the top of the screen, because the code won’t have to spin its wheels checking the hit over and over. It wastes time, but not that much. This is why UNROM games put their status lines, with the score, timer, health bar and life counters, at the top of the screen.

Well, The Guardian Legend is an UNROM game, and maybe because creators Compile wanted to show off, they decided they’d put the bar at the bottom of the screen. And yet, their game doesn’t waste most of each frame just in maintaining the status bar.

How? And what does that have to do with the Twin Famicom? For that I’m going to direct you to Nicole Express’ blog post. May you find it as fascinating as I did!

It’s only about nine minutes long so you can guess that it doesn’t go into deep detail. Essentially the NES is split into two parts, the CPU and its memory, and the PPU graphics chip and its own memory. A lot of classic consoles and microcomputers had to take special measures to support their display, which often ended up being the most complex part of the unit. Think about it: you have what amounts to a deluxe broadcast character generator right there in a box on your desk, shelf or floor, with lots of extra bells and whistles besides. (In fact, home computers were often used to generate current events channels for local cable companies, and an Amiga was essentially the basis for the old Prevue Guide channel.) It’s like a tiny special-purpose, single-receiver TV station just for your own use.

Graphics hardware is extremely timing sensitive. It has to generate the signal for your TV to display according to standardized picture generation requirements, so special requirements are often necessary. In the Commodore 64, for instance, the VIC-II graphics chip has the power to actually put the 6510 CPU to sleep, so it can have unrestricted access to the computer’s memory, without fear of bus conflicts, when it’s needed. This reduces the overall speed of the processor by a bit, and it’s why C64s turn off the screen when loading programs from cassette tape, in order to keep the CPU timing consistent relative to the data being streamed in off the tape.

The NES gets around this by giving the PPU RAM and address bus for its own exclusive use, and to put stuff in it the CPU has to use the PPU as an intermediary. And what’s more the NES exposes both the CPU and PPU’s address busses through the cartridge connector (which is why it’s got so many pins), allowing carts to supply dedicated ROM and RAM to both chips.

Even though it’s just a high-level overview, I found it a worthwhile use of those nine minutes, and you may very well enjoy it too.

That removed BCD feature. Why? The video notes that the circuits are right there within the chip, but have been disabled by having five necessary traces severed. The video notes that the 6502’s BCD functionality was actually patented by MOS, and asks, was the feature disabled because of patent issues? Was Ricoh trying to avoid paying royalties?

In the meantime, ten games from 1990 are in this episode. They are:

Puss ‘n’ Boots: Pero’s Great Adventure – Technically a retread of a previously-covered Japanese game, this version has substantial differences so Dr. Sparkle decided to cover its U.S. version separately. A very easy game until the last stage where it jumps in difficulty, and then the final boss is absurdly hard. Dr. S expresses confusion why a game made to be so easy that it’s obviously intended for young children would become nearly impossible right at the last second. Personally, I suspect it was done because NES game publishers were terrified of the game rental market.

Wit’s: A Japan-only release, this is basically a de-luxe version of Snake, where your enemies have special abilities that you have to account for. Suprisingly, it’s an arcade port!

Captain Tsubasa Vol. II: Super Striker: A weird RPG take on Soccer, published by Tecmo and based on a manga and anime series. Instead of controlling a player or players completely in real time, the action pauses frequently and asks you what to do. The main screen is mostly animations down on the soccer field. It’s a unique take on soccer, but it’s not the only one: this is the second game to play like this on the Famicom. The Captain Tsubasa game series continues even today: the most recent releases, Dr. Sparkle tells us, are on PS4 and Nintendo Switch, although I don’t know if they take the menu-based RPG approach.

Jyuouki: This is simply a licensed Famicom port of Sega’s Altered Beast, and a pretty bad one at that.

Mahjong G-Men: Nichibutsu Mahjong III: Yet another Mahjong game, although with some interesting features, if you’re into Mahjong. That’s not Mahjong Solitaire, a.k.a. Shanghai, the Activision (and formerly PLATO) computer game where you remove tiles in matching pairs from a tableaux, but the Chinese Rummy-like game using tiles instead of cards. It also has a weird Tetris-like subgame involving Mahjong tiles.

The Pennant League: Home Run Nighter ’90: Yet another Famicom baseball game.

Dr. Mario: The classic Nintendo puzzle game! I always thought it was a bit inferior to Tetris, but then most games are, and that didn’t stop me from playing a ton of it long ago.

Pictionary: Based on the board game, and coming from infamous American NES publisher LJN. Dr. Sparkle is a bit harsh on developer Software Creations, but I think this effort looks pretty well-made to me. It’s not a classic, and it’s actually not really so much Pictionary as a kind of variation on the theme, where players play mini-games to reveal parts of a drawing and then try to guess what the drawing is of. It looks much like one of Rare’s many game show and board game adaptations and creations, and in fact if it weren’t for the Software Creations credit I’d have assumed that Rare made it.

Bigfoot: From Acclaim and developed by Beam Software. It’s fairly well polished for a Beam Software title, but has some weird ideas to it, including a weird control scheme for the events that involves tapping left and right on the control pad. I think the idea has a bit of merit, but that it was probably the wrong place to use it. A Bigfoot game would mostly be bought or given to kids, who would be the absolute last demographic you should expect to master a non-standard control scheme. I’m not one of those people who thinks making a game that goes about its play differently than most other games is always a terrible idea (see: most of what I’ve ever written about roguelikes), and I can kind of see why they did it, trying to make a race game that’s more than just holding to the right. It probably could have used a bit more iteration though.

Snake Rattle ‘n’ Roll: A game from Rare that they actually put a lot of effort into, and it shows. And some people really like it, it’s definitely got a cult following. Dr. S isn’t part of it, due to the difficulty of getting used to SRnR’s isometric style. I think what happened was, they had these routines laying around that they used in implementing NES Marble Madness, and decided to do another game that controlled in that kind of way. I think the game was poorly suited to a digital control pad; if it were controlled with an analog stick, or at least a digital control where diagonal movement is easier, I think it’s possible that some people who hate Snake Rattle ‘n’ Roll might be able to enjoy it better.

Anyway, here is the whole episode, start to finish:

Another fact about J&H: the Japanese version had two full levels that were cut from the U.S. version, which replaced them with replays of other levels. It made a bad game even worse!

Now, because of Behind The Code, you know more about the Dr. Jekyll and Mr. Hyde game than many much better NES titles. Congratulations!

rodneylives

It’s 19 minutes long, and is even geekier than is usual for us, going into a disassembly of the game’s machine code in its quest to make the game marginally less awful.

As long as we’re on the topic, here’s Jeremy Parish’s NES Works episode on Dr. J & Hyde, which is also 19 minutes, and also covers the somewhat better (but not hugely so) game Amagon:

While we’re on the subject, did you know that Jekyll & Hyde has a secret ending? Both endings are shown here (4 minutes):

The “bad” ending is the normal one, and shorter, but is arguably a happier conclusion to the story. To get it, all you have to do is get to the end of Stage 6 with Jekyll. That’s all.

To get the other ending, get to Stage 6 with Jekyll, then turn into Hyde and get to the end of his version of the stage. Usually, if Hyde gets as far into his level as Jekyll has gotten into his, he’s struck by lightning and dies. But in this level he’ll be allowed to reach the end of his version of the level for some reason, where there’s a boss! Beat it, and when you return to Jekyll’s world the enemies will be gone, and he’ll be free to finish the level without harassment. However, ending events will be different….

When you post as many Youtube videos as I do, it’s easy to form opinions about their style. That of “TheRetroDude,” as he styles himself, is interesting, it’s still hyper-edited in the way that so many Youtubers loathsomely adopt, but it’s not nearly as distracting as those. He keeps the volume down, as well as the number of swoopy objects tearing around the screen like a toddler newly introduced to Toblerone.

He has good points about how extraneous the game’s scoring system is too, although his misgivings could be laid against many other games. In Super Mario Bros, score is mostly a spacer before toppled turtles start giving extra lives. I think that score isn’t a bad addition to a game as long as it’s implemented thoughtfully, yet for too long it hasn’t been. Even in the NES days it was included to give players a short term goal to aim for, when they didn’t really need it.

What would a good scoring system look like, one that rewarded skill? Well–

• Losing a life would reset score to that at the last passed checkpoint, eliminating point pressing from lives.
• Extra lives at game end would be worth a bonus each.
• Game timers are worth a small, yet substantial, award at level end, to prioritize fast play over slow.
• Awards should be given for score, most typically extra lives, but others are possible too.
• Replaying levels, and other means of “minting points,” earning arbitrary scores, should be ruthlessly eliminated. If the player can replay levels indefinitely then think about if your game really needs a score, and if it does, don’t allow players to earn more points from replaying them without costing them the points from that last pass.

Two games that come to mind that do scores well are:

• ZANAC on the NES, being a scrolling shooter without checkpointing score is generally fair, although it is possible to warp backwards does break the no-replay rule, and
• Star Fox 64, which only adds a level’s score to the player’s total at its end. SF64 is a game obviously designed around score attacks.

Where was I? Oh! Here is that video about Mega Man’s scoring system.

Mega Man 1’s Really Weird Score System (Youtube, 9 minutes)

I’ve been looking into the various home computer ports of Pac-Man lately. One of the better ones is the one for Famicom/NES, probably because it was made in-house at Namco, which I presume because while it’s by no means perfect, it has ghost AI that much more closely matches Jamey Pittman’s definitive Pac-Man Dossier than the others. This is a bit more important than the other ports because, due to the relative familiarity (that is to say, inexpensiveness) of NES emulation at this point, Famicom Pac-Man is often put in compilations, especially in dedicated consoles, instead of the arcade game. In point of fact, the Namco Museum Archives Vol. 1 that’s available for various consoles uses the Famicom versions of all its games, not the arcade, and Pac-Man is one of the included games. To tell the difference: if the score, fruit tally and lives are to the right of the screen, instead of above and beneath it, and Pac-Man looks a little too big to fit in a maze passage, then what you have is an inferior home conversion.

How is it different? Well:

• The sound of Pac-Man eating dots is much worse, for starters, it never fails to bother me.
• More substantively, the ghosts have slightly different constants in their chase routines: it’s slightly harder to fake out the Pink ghost (Speedy/Pinky), and the Orange ghost (Pokey/Clyde) gives up the chase a little more reluctantly.
• The timing for scatter periods, relative the speeds of the ghosts, is a little off. Scatter periods are usually slightly longer.
• The speed of the game as difficulty increases is also a little off. In the arcade, the First Apple board (Level 5) marks a noticable increase in Pac-Man’s speed, but it seems to happen around the Second Orange (Level 4) on Famicom. Yes, that’s how much of arcade Pac-Man and its port that I’ve played-it could be subjective, but maybe it’s not.
• The bug that affects Pink’s and Blue’s (Bashful/Inky) AI when Pac-Man’s facing up doesn’t exist here.
• When ghosts enter Scatter mode, they don’t reverse direction. This makes the game easier (one less sudden reverse to throw you off) and harder (no obvious indication that the ghosts are scattering, and one less thing to throw them off from immediate pursuit).
• As the game advances in difficulty, in the arcade, on the 4th Key board (level 17), the ghosts won’t turn blue and vulnerable when you eat an Energizer, and instead will just reverse direction. And from the 6th Key (level 19) on, the ghosts will never turn blue again! NES Pac-Man instead gives them a very tiny bit of blue time, about a half-second’s worth. It never reaches a state where the ghosts become completely invulnerable.

And at last, the bug which I have confirmed. On the 10th Key board (Level 22), and every level thereafter, the ghosts will start out in an unusually long Scatter period. Their usual habit is to emerge from the box in the center of the screen and move to a corner of the screen, and circle there for a few seconds. Pink goes to the upper-left, Red (Shadow/Blinky) to the upper-right, Orange to the lower-left, and Blue to the lower-right. This period is called a “Scatter Mode” in the Pac-Man Dossier.

In most levels, presuming you don’t lose a life, the ghosts will enter Scatter Mode at exactly set three times: from the start, about 25-or-so seconds in, and about 30 or so seconds after that. These periods are usually five seconds long. There are some minor details I won’t get into-you can read the Dossier for those. These periods are lifesavers for intermediate Pac-Man players playing without patterns, as they are the only really safe ways to access the bottom passages of the board without getting trapped or wasting an Energizer.

Each Scatter Mode is only supposed to last five-to-seven seconds, but on Level 22 and after, all of the Scatter Modes last around 20 seconds. Here is the bug in action, demonstrated in Namco Museum Archives Vol. 1:

Why would this board be different from the others? In the arcade, the 9th Key (Level 21) is the maximum difficulty the game reaches. Any pattern that works on the 9th Key level will work for the rest of the game, all the way up to the kill screen on Level 256. It seems that, on the Famicom/NES version, after that level the game may not have data for the level to follow? But I haven’t looked at its code to know for sure. Maybe I should make that a future project.

The Commodore games that won out are Ballblazer, Castelian, Die Hard (but the C64 version’s really different), Ghostbusters, Ghosts ‘n’ Goblins, Q*Bert and (surprisingly) Smash T.V. Decent C64 games that nevertheless lost are Blades of Steel, Commando, Donkey Kong, Mighty Bomb Jack and Super Mario Bros. (rated were both the similar Great Giana Sisters and the recent fanmade version of SMB that uses advanced scrolling tricks). Gyruss, Mario Bros. and Pac-Man were rated at a tie.

Used to be if you had a new computer you wanted families to buy, you had to have a version of BASIC to ship with it. The Apple II had two, one written by Steve Wozniak himself. Right off the top of my head, computer systems with BASIC, go! Altair, Apple II, Commodore Pet, Vic-20, 64, 128, Plus-4, 16, Atari 8-bit, TRS-80, MS-DOS, Windows (Visual BASIC carried the torch for many years), and, most improbably, the Atari VCS/2600, in its BASIC Programming cartridge, an effectively useless cart for its stated purpose that’s nonetheless an excellent hack. The machine has 128 bytes of RAM, but it can still run BASIC, by jove.

The Famicom has a version of BASIC too, coming in at the end of the language’s heyday. Over on the Peertube instance diode.zone, user RE:Enthused did a two-part introduction to it that may be of interested to people who still think in terms of FOR/NEXT loops.

Let’s look at Family Basic on the Famicom, Part 1 (8 minutes) and Part 2 (17 minutes).

The post mentions that designer Shouichi Yoshikawa, a.k.a. “Angela,” has an interview up at GDRI. It also mentions that Angela used to have a site devoted to their game, which while gone now has a backup on the Wayback Machine! Sadly the promised English version of the site never materialized.

The gist: while each scanline is being prepared for display, the NES’ PPU looks through the entries for the machine’s 64 hardware sprites in order, finds the first eight that will display on the current line, and copies their attribute data to a small area of internal RAM. There is only space there for eight sprites, so, the NES cannot display more than eight sprites in a single scan line. Any later sprites in the primary attribute data won’t have room to be copied, and so the PPU won’t be able to display them.

One thing it notably doesn’t cover, however, is how games implement priority shuffling to cause sprites to flicker instead of not display at all. The video suggests that that might be coming in a future video….

This episode presents ten games from June of 1990, well into the glut of NES games when many companies with no business being in the games business dipped in their toes, much as they did at the end of the Atari 2600’s reign. Even though Nintendo was supposedly guiding the library with their benevolent white-gloved hand, those of us who were alive then and lived through it know better.

The games:

• Bandit Kings of Ancient China (a.k.a.. Suikoden): Dr. S has some fun with the opening of this one, where he confuses it with a different, much later, much prettier game called Suikoden. This one is another of Koei’s many historical sim strategy games, ports of computer games. These games aren’t actually bad, but they are definitely an acquired taste, and they’ll destroy you if you aren’t prepared. I wonder how these games look internally? There doesn’t exactly seem to be a huge Koei historical strategy sim romhacking scene. Internally I imagine them being a giant maze of 8-bit math routines and text tables. If NES-era JRPGs are anything to go by, lots of menu-based games like this are riddled with subtle bugs. Someone should look into that. Someone other than me.
• Kickle Cubicle: Also not that bad a game, a fairly charming port of an arcade puzzle game. Someone should have told Irem that no one was making good NES games around this time, because this is a highlight of the episode. Sadly it’s not to Dr. Sparkle’s tastes, but he admits it’s not really that bad. (Apparently he got beat up by Koke the Eyepatch-Wearing Chicken.)
• Moero!! Judo Warriors: A judo sim from Jaleco’s “Moero” series (which doesn’t contain Moero Twinbee as one might think or hope). Many of the Moero sports games got localized to the US under different names (the baseball one became Bases Loaded). It’s largely a redo of an earlier Jaleco judo simulation.
• Jeopardy! 25th Anniversary Edition: Agh, another of the avalanche of Rare-developed game show adaptions from the NES era. At least Jeopardy still exists today so you roughly know what’s going on, as opposed to the hates of Double Dare or Remote Control. No great shakes, no, but at least look at the spinning words “Anniversary Edition” on the title screen. Rare would often put that bit of unnecessary polish into their work. Despite their efforts though, this is not a game that plays well with a gamepad.
• Heavy Shreddin’: A snowboarding game from Imagineering, it’s pretty basic.
• Cabal: an adaption of an arcade game, programmed by Rare. (But remember, there is no cabal!) You might call it an Operation Wolf-like, but with destructible terrain. On the NES it’s not a lightgun game, even though it looks like it wishes it were one.
• Silk Worm: Another arcade port, on the NES is lacklustre side-scrolling shooter where you can play as a helicopter or a jeep. Keep in mind, as you watch the footage of this, that Super Mario Bros. 3 came out the year before in Japan.
• Arkista’s Ring: the cover seems to promise at last the Zelda where you play as Zelda, but no, it’s not an exploration game at all. Not really bad, but not a system highlight. As Dr. Sparkle says, the game pulls a Ghosts ‘n Goblins on you, making you compete all the levels four times at higher difficulties. Hm.
• Rad Racer II: Pretty much a track update of the original Nasir-developed Rad Racer, and Square’s last non-RPG game for a long time, as well as their last Famicom game. Rad Racer was a modest hit when Nintendo published it for the NES, so Square probably sought to capitalize on that with this US-only release.
• Rocket Ranger: A port of the Cinemaware computer game. Cinemaware’s gimmick was making games that mimicked the experience of movies, and this one’s no different. In actual play it’s just a minigame collection within a simple strategy framework.

And as an extra, Dr. Sparkle presents his 1990 arcade round-up. Games covered are Sega’s Alien Storm, Moonwalker, GP Rider and Columns, Atari’s Batman, Race Drivin’ and Pit Fighter, Capcom’s Mercs, 1941 Counter Attack and Super Buster Bros., Konami’s Aliens and Parodius Da!, Namco’s Final Lap 2, Irem’s Air Duel, Williams’ Smash T.V., SNK’s Beast Busters, and-oh wow!-Seibu Kaihatsu’s Raiden!

It’s been a long time… before Hardcore Gaming 101, before Kotaku or the Angry Video Game Nerd, before 1UP, Joystiq and a bunch of other sites still living and defunct, there was |tsr’s NES Archive. While it only lived for four years, hasn’t updated in 23 years, and all of the images are broken now (a huge shame for some of the features), it’s still online, still ready to give you their humorous take on old video games. Long may it continue beaming out its snarky message. Consider that the time between when the NES was released, 1985, and |tsr’s archive shut down, 2000, was only 15 years. And that time isn’t getting any longer, while the time since it shutdown is. I’ve said it a lot here lately, but: time is cruel.

A few notable features there:

• An interview with Ed Logg, identified as the developer of NES Tengen Tetris but also one of the great designers of Atari, programmer of Asteroids and Gauntlet.
• A collection of NSF music files, playable in a variety of ways including, as the page indicates, in WinAmp.
• A list of old gaming sites, useful mostly as a base for finding things on the Wayback Machine. It’s interesting to note where some sites redirect to. Domain guardianship of some old domains were handled by Classic Gaming (classicgaming.com), but because IGN didn’t care enough to keep it viable those sites just redirect to the IGN main page now. Poor form. Sites that you can still reach (sometimes through intermediary sites) through their links are eBay, the Howard & Nester comic archive and the Japanese site Classic Videogame Station Odyssey.
• And the meat of the site, their pages of reviews of NES games, pirate and bootleg games (sadly with dead images), NES books and ads (also with all broken images) and merchandise (images: nil).

The images, I note, are not broken so much as forbidden access. It’s possible that tsr’s web host, Atari HQ, still has them but has misconfigured the site. Atari HQ is still up, but now seems to only be an aggregator for other sites’ content. I wonder if an email to the right person might restore access to that entire swath of early web and videogaming history, or if they’re completely asleep at the switch?

However, with Chrontendo it’s worth it. Dr. Sparkle’s epic-length tour through the entire run of the Famicom’s and NES’s libraries. Most episodes are an hour or longer, but you definitely get your time’s worth by watching them. And like U Can Beat Video Games, it’s nice just to have running in the background while you do other things.

We linked to Chrontendo #60 last June, titled “The Most Perverted Episode.” Sadly Chrontendo #61 doesn’t come with any titillation factor; it’s title is “Not really worth the wait.” It’s a series of games ranging from pretty bland to outright terrible. Covered are the months of May and June 1990, plus one game that’s a holdover from April. Within the video is footage and commentary on:

• Castle Quest, which is not the same game as Castlequest in the U.S., which was a renamed localization of a game called Castle Excellent in Japan. It’s a turn-based strategy game that’s like Chess against a computer opponent, but with a random factor.
• Ys II: Ancient Ys Vanished: The Final Chapter, which isn’t so bad, but was greatly overshadowed by the must more impressive Turbografx CD version released around the same time.
• Baken Hissou Gaku: Gate In, yet another horse racing sim, this one with an extremely bland presentation.
• Jajamaru Gekimaden: Maboroshi no Kinmajou, a so-so ninja adventure/Zelda clone.
• Snake’s Revenge, the disowned sequel to Metal Gear that Hideo Kojima didn’t work on, a game that some people like but Dr. Sparkle doesn’t. I’ll say it’s more polished than NES Metal Gear, at least.
• Remote Control, a video version of a nearly forgotten MTV game show that couldn’t use any of the celebrity likenesses from the show.
• Chip ‘n Dale: Rescue Rangers, another of the Disney Afternoon tie-in games. Dr. Sparkle admits it’s not bad, and it’s probably the best game of the episode, but is only really interesting when played co-op with two players. There’s a fairly scandalous piece of Gadget fanart here, scavenged from the aptly-named halls of DeviantArt.
• Rally Bike, a port of a Taito arcade motorcycle game with much less polish than the original. I note that this game was ported by one of my un-favorite developers, Visco.
• Battle Fleet, another turn-based strategy game, with a naval theme.
• And S.C.A.T.: Special Cybernetic Attack Team, a game that plays a bit like Capcom’s Forgotten Worlds, but without that game’s hallucinatory visuals.

On Romhack Thursdays, we bring you interesting finds from the world of game modifications.

Gradius for Famicom and NES is a well above-average port of a game for very different hardware than the arcade original. It was good enough that it was converted right back into arcade game, released for Nintendo’s Unisystem arcade hardware as Vs. Gradius. Graphically and aurally, it is quite similar to the arcade game.

It’s similar, but not identical. Now this hack doesn’t change the major downgrades from arcade Gradius. There is no vertical scroll in levels two or three, and you still can only have two Options at once. But in a variety of subtle ways, the game looks a bit nicer. In particular, the game’s text fonts being changed from the boring old font used on the NES back to the arcade’s snazzy line-drawing affair is a nice change.

The original version of this is quite an old hack, created back in 2000, but it has been periodically updated over the years, most recently changed in 2018. That’s a long period of support for a romhack!

They’re all interesting, but the one that floats my particular boat is the third, which turns into a deep dive in the compressed manner that Super Mario Bros. stores its levels in ROM, and uses to draw them during play in real time.

On Romhack Thursdays, we bring you interesting finds from the world of game modifications.

They have fallen into obscurity in the intervening decades, but it used to be that the Ultima games were some of the biggest RPGs around, and many still have fond memories of them. The story of the rise and fall of Origin Systems, once one of the biggest game publishers, and how now they’re just another of the hundred ignored lines on EA’s balance sheet, is not our business here today, but instead that of one fan’s effort to improve one of the less faithful adaptations: the NES version of Ultima Exodus.

Ultima and Ultima II (and their predecessor Akalabeth) were popular, but Ultima III was the first megahit version of the game, that could be considered to stand up today. Ultima I was pretty small, and Ultima II had a lot of crazy elements like space travel. Ultima III has a much more cohesive game world, a more detailed quest, and generally feels a lot more like what we would consider an RPG game now. Later games would build off of it and become even more popular, especially Ultima IV with its detailed morality system, and Ultima VII with its vast game world, depth of NPC interaction, and many system and UI improvements.

Back to Ultima III. One of its best-selling versions was the Famicom version in Japan, which had a bit of a media blitz around its release. Both the Ultima and Wizardry games had something of a second life on Japanese computer systems and consoles, where they would go on to sell millions of copies more. While EA’s ownership and neglect have meant that Ultima is mostly gone and forgotten*, in Japan new Wizardry games continue to be made, hewing to that series’ original dungeon crawl aesthetic.

* This is, honestly, partly to series creator Richard Garriott’s ownership of several important characters, meaning both parties have to agree to the other’s vision for any further official Ultima game to be made. And Garriott seems to be chasing fads lately; his most recent idea for a game utilizes that bane of all game design concepts, NFTs.

So now you have a little idea of what Ultima is. The Famicom/NES version was a hit in Japan, but it differs from the computer version in many ways. This was pretty much the norm for the many Japanese-made Famicom adaptations of Western games. An article could be usefully written on all the ways Famicom ports of RPGs differ from their originals. Maybe later.

The point of this romhack is to change the NES version of Ultima III: Exodus so it more matches up with the computer versions. It uses its own patching system, so Romhacking.net’s web-based patching system won’t be of use.

So many little things have changed in this version that it’s hard to talk about! At the very least, the graphics have received a complete overhaul. The cartoony figures of the original, which were pretty silly even back then, look a lot more appropriate for a series with the stature and legacy of classic Ultima games.

NES Ultima Exodus is also notorious for a number of significant bugs, including the absence of an important clue, it being impossible to cancel a character’s turn without wasting it, poorly differentiated character classes, and the lack of some of the monsters of the computer version. These have been fixed in this version. Some other niceties have been added, including character portraits for the people you talk to, which is really going above and beyond for a game like this!

It’s pretty much become the definitive console release of this landmark of computer RPG gaming! You should check it out if you have an interest in these things.

Portopia is the biggest missing piece, to many US enthusiasts, of the history of Japanese gaming. It led to the creation of Dragon Quest, but it had a huge influence all on its own, which can be felt in a wide variety of other Famicom titles, including some that did make it to the US. Why do The Goonies II and Dr. Chaos have those weird room-based adventure sections? It’s because of Portopia, trying to mix its kind of menu-based first-person gameplay with the pre-existing side-scrolling platforming game style popularized by Super Mario Bros. It seemed random to Western players at the time, but Japanese players would have known exactly what those games were trying to do.

We’ve mentioned Jeremy Parish and his various Works projects before, and they’re always interesting and informative, a great antidote to the strident style of many popular Youtubers, and this one is especially important to anyone seeking to understand how the Japanese game industry grew and evolved in the Famicom era.

On Romhack Thursdays, we bring you interesting items from the world of game modifications.

We’re starting another weekly feature on Set Side B, where we try to regularly bring you news on new romhacks and romhack-related items. Big websites sometimes seem like they try to appease publishers, whose good graces they rely upon for news and review copies, by not mentioning hacks too prominently, at least if they’re of console games. Whether this happens, or if it merely seems like it may happen, we don’t ask big publishers for review copies so we don’t have to avoid talking about them, and are free to tell you about the most interesting of these game edits that we can find.

To start us out though, something you’ll find you’ll need if you make heavy use of hacks, are good rom patchers. To shield themselves from legal liability, hack authors usually distribute their modifications through the use of patches, which are in essence lists of modifications that can be applied in an automated way to a source rom file, which you’ll have to source by some other means.

Two good such utilities are Floating IPS, which can apply IPS patches, and (the sadly departed) Near’s beat, which can apply BPS patch files. IPS is the most commonly-used utility, and functions mostly as a kind of binary diff, but it’s limited to source files of a maximum size of 16 megabytes, and doesn’t offer any error detection features, so if the file you’re patching isn’t exactly what the patch expects (which happens frequently, as bad dumps or headerless roms often turn up), not only will you end up with a corrupted file, but you won’t even have any indication something has gone wrong-in most cases, you’ll still be told the file patched successfully. BPS is a more intelligently-designed system, and has some error detection built-in.

A new utility that can be of use is “Advanced NES Rom Utility,” a program that can not only apply both IPS and BPS patches but several other types as well, and can also fix many common problems with NES dumps in particular, including fixing checksums and metadata. But patches are usually source platform agnostic, so you might get some use out of it even if NES romhacks are not interesting to you.

Nicole Express regularly has great long-form posts, and this one goes into some detail about Famicom and NES mappers and how they were used to extend the capabilities of the system.

Nicole Express: What made the NES so interesting?

Here at Set Side B our purview is “Indie, Retro, Niche,” and we consider romhacks, of the niche, to be among the the nicheist. (Nietzsche-est?) But there are lots of romhacks, with more every day, and most just aren’t that newsworthy.

This one’s pretty interesting though? As the Romhacking.net entry mentions, Raggedy Ann, while once a pretty big pop culture property with an animated movie and two TV specials directed by Chuck Jones, has fallen into disuse for decades due to rights issues.

The linked hack, for Data East’s Famicom McDonalds tie-in game Donald Land, is an attempt by Garrett Gilchrist and Brooklyn Williams to simulate what a Raggedy Ann game from the NES era would have been like, using graphics and characters from different iterations. Here’s a scene with The Greedy, from the feature cartoon, that once inspired many a nightmare:

Pretty cool, and rather more ambitious than your standard pedestrian graphics swap!

It’s been known for a while that three classic-era Atari arcade games were produced by HAL for the Famicom and NES: Defender II a.k.a. Stargate, Millipede, and Joust. Nicole Express recently did her typically excellent job discussing them and what makes them interesting. Such as, among other things: they use music that was later reused in NES Punch-Out!!, they are subtly different between their Famicom and NES versions, Satoru Iwata may have personally worked on them, and they were developed as part of Nintendo’s pitch to Atari to have them distribute the NES in the United States.

Something that one might overlook reading the article, however, is the news that this isn’t the only version of Millipede made for the Famicom hardware. As an in-house project at Atari Games/Tengen, Ed Logg himself implemented Millipede for it, before they discovered that the publishing rights in the US resided with the other Atari, the one that got bought by Jack Tramiel.

The source was recently found on a backup tape from Atari, and hand-assembled. The resulting rom file can be downloaded from the AtariAge thread on it. It has no sound, because that hasn’t been implemented yet, the colorful alternate palettes of the arcade version are missing, there are some bugs (I mean program bugs, not enemies), and the DDT Bomb objects hadn’t been put in yet, but a lot of the game is still there. There are even multiplayer modes, supporting up to four players playing alternating or simultaneously! It’s especially interesting since Ed Logg assisted Centipede’s creator Dona Bailey in creating the original game.

There was an error in the data prep in many NES games that caused them to reverse the bit order of samples. Or more accurately, the games encoded the samples correctly, but the flaw is in the NES sound hardware.

The result is, many games with samples sound notably worse than they should. The most infamous example of this is the sound in Double Dribble, which sounds particularly bad on its title screen. The difference can be heard on the game’s page on The Cutting Room Floor. There’s a hack for Double Dribble on romhacking.net that corrects the samples in-game.

Another game this affects is the unlicensed Tengen NES game KLAX. In the arcade KLAX had very little music, but the NES version has excellent music that relies heavily on sampled instruments. There’s a fixed patch for that game on romhacking.net, too!

Chrontendo’s back! Dr. Sparkle’s long-running journey through the entire library of the Famicom and NES continues. He’s been doing this for at least 15 years! Chrontendo got its start as a blog, then moved to a YouTube format, although every episode is also uploaded to the Internet Archive. Dr. Sparkle tries to complete the games he covers, meaning, sometimes it takes a very long time to construct an episode, especially when it contains a lengthy JRPG.

In addition to being generally watchable by anyone with even a passing interest in video gaming history, Chrontendo is a good series just to have on in the background while you do other things. What I’m saying is that it’s comfortable. Like Comfortable Doug! (warning: earworm)

Chrontendo 60 is subtitled “The Most Perverted Episode,” covers April through May of 1990, and features:

• horse racing sim Kurogane Hiroshi No Yosou Daisuki! Kachiuma Densetsu,
• a long section the original Fire Emblem and the series in general,
• Rare’s PinBot, a very unique and interesting simulation of a real Williams pinball table with some unique video extras,
• GameTek’s home version of the Nickelodeon game show Double Dare, which was also made by Rare,
• the ludicrously-titled Dinowarz: The Destruction of Spondylus,
• Imagineering’s Ghostbusters II,
• Ivan “Ironman” Stewart’s Super Off Road, by Rare,
• a very long section on the epic Final Fantasy III, from and by Square, which Dr. Sparkle proclaims to be the best JRPG on the system,
• Kagerou Densetsu, a “sorta action RPG thing” published by “Pixel,” but we’re not sure who exactly that is, and may have been intended, it is speculated, to be a kind of RPG-ish sequel to The Legend of Kage, and
• Nintendo World Cup (forgive me for not typing out the entire Japanese title), that weird Kunio soccer game that Nintendo published under their own banner, just with all the story and setting removed. It’s a decent soccer game even so.

With this episode, Dr. Sparkle is declaring a dividing point for the series. Up until now has been the rise of the Famicom; the rest covers its fall, what he calls the “Byzantine Empire” phase of the system’s life. This doesn’t mean the series is almost over though. Far, far from it.
