Romhack Thursday: Astro Smash ‘N’ Blast!

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

Most of the things we post here are game hacks. That is, something that has been modified from a published game. Hacking games is not illegal, but the process that some people usually use to obtain the roms themselves may be somewhat questionable. Well not for the subject of this week’s article: it’s 100% homebrew, created from scratch and unencumbered by such considerations! It runs on NES hardware (or an NES emulator), but technically speaking what we have here is more of an indie game on classic console hardware more than a hack.

It’s also an unusual subject for a 2022 indie game. You’ll find all kinds of hacks to, say, put silly characters into Super Mario Bros., but a remake of an Intellivision game, and one with an Atari port that is very much its equal, and porting those games to the NES-that’s unusual enough to merit discussion, even if the game itself is very simple.

Astrosmash! (with the exclamation point) was a very popular game for the Intellivision. I heard it was originally intended to be an Asteroids-style game, with rocks that split into pieces when shot, but turned out to be interesting translated to a Space Invaders-style missile base game, where your ship is stuck to the bottom of the screen shooting at targets falling from above. Astroblast! was released by M-Network (Mattel’s label for publishing games for competing systems), and was a very similar game for the Atari VCS/2600, but actually improved on the original in two ways: it can be played with either the joystick or paddle controller. It’s the only game for the VCS like that! Both control schemes are fun, although experts can probably play much better with the paddle, due to both its faster and more precise movement. And, it’s extremely fast! The sheer pace of the VCS Astroblast is so much greater than the Intellivision Astrosmash that it kind of demonstrates why VCS games tend to be more engaging than Intellivision games: it wastes no time with an easy ramp up in difficulty, but starts faster than almost any other game, and only gets harder from there. It’s simply exhilarating!

The way it works is like this. Rocks, Pulsars and Spinners fall from the sky, and your ship tries to shoot them before they hit the ground. You get points for shooting things, but lose points for things that get past you. Rocks come in two sizes (smaller ones have higher point values), but only kill you if they hit you. Big rocks break apart into small rocks when stuck. Pulsars home in on you as they fall, which makes it more likely they’ll hit you, but also means they’re easier to shoot. The most dangerous items plummeting towards you though, by far, are the Spinners. You must shoot Spinners, you don’t just lose points if one lands but a life. Small Spinners are your greatest enemy, since they’re also hard to hit. There’s also UFOs that harass you, which pass by horizontally and drop bombs on you.

Here is a short game of Astroblast, to give you a sense of how it works. Notice how fast it is. Know that this is nowhere near as fast as it gets. It is my kind of game:

As you score gets higher, the background color changes, and the game gets faster. You get extra lives every 1,000 points, and you start with ten, far more generous than most arcade-style skill tests from that time, but you need all those lives because you’re constantly dying. Difficulty is determined by score, the more points you have the faster it gets. Because you lose points as well as gain them, and because the speed is balanced right at the edge of human reaction time, players tend to play until they reach a difficulty score boundary, where only nearly-inhuman focus, and lots of practice, can push you beyond it. Astroblast will push your playing skills to the very limits.

Astro Smash ‘N’ Blast is an homage to these two games. It takes the same form, your ship at the bottom shoots upwards at an endless wave of plummeting targets, Rocks, Pulsars and Spinners. (There are no UFOs in this version.) There’s fewer things falling, but the game is a bit more precise about hitting small targets. Pressing the Select button turns on autofire, which you’ll probably want to use, to avoid compressing your thumb tissue into a singularity with rapid frantic tapping.

Rocks don’t split in two in this version, but otherwise it plays a lot like VCS Astroblast. Small Spinners are particularly difficult targets to hit, and must be aimed at precisely.

This version takes on a bit of inspiration from Pac-Man CE, in that in addition to having limited lives, you have a time limit. You can earn extra time by hitting +30 second targets that pass by horizontally, and you can regain hits on your ship by hitting passing 1UPs. These are the only bonuses; unlike the originals, you don’t get extra ships from points at all. Although the game ends if you run out of time, chances are great that you’re going to lose all five of your lives before then.

As in Astrosmash/blast, as you ascend to tougher difficulties, the screen’s background color changes. You probably won’t see the later levels though without a lot of practice. Astro Smash ‘N’ Blast offers a level of challenge rarely seen in most games. I prefer games like this, with a strong element of chaos, to more typical modern examples of high challenge, like bullet hell shooters and rhythm games. I think the essence of the super fast video game is in randomness, not memorizing levels and playing them almost by rote but in reacting instantly to dynamic situations, and that’s why I like all the Astro-style games.

I am left wondering what inspired Double Z to look to old Intellivision and Atari games for inspiration. They were released when I was a small child; had Double Z even been born yet when the Astro games were on store shelves? For whatever reason they made it, I am glad they did. Games like this don’t come around often any more, and I intend to put in some solid practice on it.

A Retro-Focused Guide for Dance Dance Revolution Beginners

Image from Mobygames

Racketboy has a great article about getting started with Dance Dance Revolution at home. DDR is still kind of going in U.S. gameplaces from the 2016 release of “Dance Dance Revolution A,” but hasn’t received a home release in that country since the days of the Wii, in 2011. That leaves options to picking up a home machine, finding a version for an older console, or, of course, yarr. Thanks, Konami! Your attention to preventing access to your products is ridiculous and easily mocked!

The ultimate decision reached is to play DDR Max or Extreme 2 on a Playstation 2, and on a CRT if at all possible, but the article contains a number of options that may be more workable for you. Dance on!

The Castlevania Dungeon

I must admit though, the NES era Castlevania logo is so much better than this one.

I love finding something on the internet that still exists after decades, and one such site is Kurt Kalata’s The Castlevania Dungeon (“This site uses HTML and CSS”) which, surprisingly, updated again last year, nine years after its previous update. Although, it was mostly a catch-up post just to let the world know it probably wouldn’t be updating again.

Kurt has moved on to Hardcore Gaming 101 since then, which build an amazing repository of classic gaming information, tore it all down, and built it up again. Meanwhile the Dungeon continues carrying all kinds of useful information on 35 years’ worth of games.

It’s what the Web was meant to be: obsessive fandom over a single game series, presented in straight HTML markup.

I’ve said before that I am heartsick for the era of the internet where the web was rife with sites like the Castlevania Dungeon. Yet, like that one video store here in my town that somehow survives even now, it persists, and that lifts my spirits. I know it’s too much to expect it to last forever, but I hope it does.

The Forum gives a Bad Gateway error, it is true, and of the main sites on the Links page only five of the 16 still work -one of the broken ones is the site for Konami of Japan. The internal pages other than the forum seem to work though. They lists all the games, has pages for artwork and music, and tries to untangle the storyline. It has a collection of fan fiction. It even hosts a few shrines to individual games, with an entertainingly lo-fi shrine to Aria of Sorrow.

Aria of Sorrow Citadel creator xenx2 still lists MSN and AIM as contact points. Hopefully they still watch their HoTMaiL address! What you can’t see here is the animation on the dripping blood at the top.

This is what the web was about, in the early days, and, I think, it’s still among what it’s best at.

Sundry Sunday: The first episode of Saturday Supercade

This is a real rarity. Saturday Supercade has, to my knowledge, never been officially released on any media format. All of the tapes of this show date back to their original broadcasts in 1983-5. I’m sorry for the poor quality, but this is from a tape almost certainly recorded off of live television nearly 40 years ago.

The year 1983 was such a weird time in media history. Take for instance the movie Joysticks. A cheaply-made culture cash-in, essentially the Supervan of its decade, it was a teen sex comedy themed around arcades, and it could only have been released in 1983. In 1982 games were big, but it takes time for a movie to be made. In 1984, US arcades and consoles had crashed calamitously, and any projects in production would have been cancelled. Saturday Supercade also dates from 1983.

Saturday Supercade was a Saturday morning cartoon show that hosted a variety of different game characters and universes. By no means a classic of animation, there’s still a lot of interesting things about it. Donkey Kong gives Mario and Pauline their modern names (decided on around the time of Donkey Kong Jr’s arcade release), and Donkey Kong is voiced by legendary early TV children’s entertainer Soupy Sales.

Frogger is depicted by the show as a reporter for a swamp’s newspaper. Q*Bert is a student in a 50s-styled high school, and other characters (including a girl Q*Bert, “Q*Tee,” not seen in the game) are imagined as his friends and rivals. Donkey Kong Jr has the young ape searching for his father, while assisted by a greaser. Pitfall’s cartoon is not only the sole home-original game to be featured on the show, but also lent two of its characters, Pitfall Harry’s niece Rhonda and mountain lion pet Quickclaw, to cameo roles in the game’s sequel Pitfall II: Lost Caverns. Kangaroo and Space Ace were introduced in the show’s second season. Yes, somehow, it got a second season.

The Wikipedia page of the show notes that episodes of Space Ace were once shown late at night on Cartoon Network, and once in a while can be spotted between shows on Boomerang, while “The Best of Q*Bert” is available as a print-on-demand DVD from Amazon. Other than that, many episodes are lost outside of master reels held by whatever company owns Ruby-Spears’ output these days, which I expect is Warner Media. There’s tons of Saturday Morning shows that are lost; this one only survives to us in any form because classic video games have oddly persisted in this weird cultural cul-de-sac, the same one that made Wreck-It-Ralph an improbably hit for Disney.

So please, enjoy, or else, experience whatever substitute for enjoyment you can bring yourself to feel while watching an old old kids cartoon from the classic arcade era. Queasiness? Unease? Existential dread?

Metroid Prime’s Save System

Zoid Kirsh on Twitter (while Elon Musk hasn’t completely wrecked it yet) tweeted about how Metroid Prime’s save system works. Metroid Prime save files are less than 60 bytes long! A single Gamecube memory card block is eight kilobytes, so it’s a bit overkill, but it’s still nice when a developer is frugal!

Image, of Metroid Prime’s inventory screen, from Mobygames.

The way they explain it is that the game has a number of “world layers” which determine what is spawned in each area when it’s loaded. Which layer is active when a room is loaded is determined by a single bit in the save. That, plus some basic stats like health and ammo, and the record of object scans, all take up very little memory when bit-packed.

If Metroid Prime’s save file were 59 bytes long, that would mean it had 472 bits to work with. The passwords used by the original Metroid only stored 144 bits of data!

Romhack Thursday: Super Mario 64 Reduced Lag

It’s not so much a hack as a recompilation, but it’s distributed in patch form so I’m accepting it. A person identified as “Nintendo 64 Wizard” took the source code created by decompiling Super Mario 64, and, simply, did something that Nintendo didn’t do: compile the game with -O2 optimization turned on. The result is a much more consistent frame rate.

From the romhacking.net article, a scene from the star with Bowser’s Sub in it, which is notorious for causing the game to lag.

If optimizing Super Mario 64 is an appealing concept to you, you might be interested in some of the videos made by Youtuber Kaze Emanuar, that goes into why the game has lag, and his own efforts into improving it.

Pitfall II: Arcade Version

Have no fear, we’ve not forgotten about Arcade Mermaid, our regular classic arcade feature. I don’t think this post is quite the right material for it, but it’s still very interesting.

People who played the Atari VCS, later renamed the Atari 2600, will no doubt remember David Crane’s seminal Pitfall!, one of the greatest, and certainly one of the best-selling, games for the system.

Pitfall’s huge success spurred the creation of a sequel, Pitfall II: Lost Caverns, which is certainly among the most technically brilliant games for the VCS. We recently covered how one of its best tricks was how it managed to get music out of the Atari’s TIA chip that few other games were capable of. That’s not all it did. Pitfall! was one of the very first exploratory platformers, and Pitfall II expanded its focus greatly. Some might call it the first Metroidvania, although it doesn’t have the item-based progression gating usually associated with that genre.

It does have great design ingenuity though. It gets its challenge not through limited lives but its huge and complex system of caverns. In fact, it abandons lives entirely, replacing them with a checkpoint system, another possible first. Getting “killed” never ends the game, instead, it just costs points and returns the player’s surrogate Pitfall Harry to the last cross he touched. So anyone, given enough time and effort, can finish the game; they might not have a good score when they do it though, which still leaves room for players to improve.

Pitfall II, with its huge world and great music on a system not known to be able to support either, powered by a custom microchip that Crane himself designed, called the DPC, would undoubtedly have been a giant hit if it had been released a year before. Sadly, it came out right at the end of the VCS/2600’s life. Crane had hopes that the DPC would help revive the system but, sadly, it became the only game to utilize it.

But that wasn’t the end of Pitfall II. While it was designed around the limitations of the VCS, it received ports for several other systems, including the Apple II, the Atari 5200 and Atari’s 8-bit computers (which both had a secret second world to explore after finishing the first!), the Commodore 64 of course, Colecovision, MSX, SG-1000 and ZX Spectrum. It even got a kind of NES port, called Super Pitfall, which was programmed by anonymous NES contractor Micronics and is widely regarded as terrible. And then, there was the arcade version.

Sega’s arcade version of Pitfall II is more of a recreation than a port! It’s divided into levels and goes back to the standard arcade paradigm of limited lives. Its first level resembles a condensed version of the first game, with some extra hazards built it. The game world is both smaller and harder than the original, to make it harder to master and thus entice players to put in more money. You can see for yourself in the below playthrough, a deathless run up on the Replay Burners channel. Videos on Replay Burners are done cheatless and without tool-assist, so you can be assured that an actual player performed this run and not a control script. The video is about 27 minutes long.

The Issues With NES Teenage Mutant Ninja Turtles

The title refers to the original NES TMNT, not the arcade version or the NES game based on it. This is the version that Konami released under their Ultra label. It sold well (real well!) but is widely considered an inferior game for a number of reasons. Those reasons are the subject of these three videos, from Youtube channel Displaced Gamers. I recommend them, even if I think every place they say gamer it would be more proper to say player.

The first video:

In a long and difficult game, one of the hardest sections comes relatively early. The only swimming section in the entire game, players must maneuver their supposedly-aquatic surrogates through a difficult course that has imprecise movement, water currents, high damage, instant kill hazards, a strict time limit, and, as the video shows, buggy implementation. Many players in the NES era gave up at this point, which is rather a shame considering it’s only at the end of level two. This video examines the code and demonstrates why it’s so challenging, and how it could be made fairer.

The second video:

TMNT has notoriously floaty jumps, a low frame rate, and a fairly weird implementation of gravity. Any platform game that allows players to adjust their jump height according to how long the hold down the jump button is fudging its physics behind the scenes, but TMNT does it rather poorly.

The third video:

Displaced Gamers examines additional problems with the game’s timing, particular with that of its input reading and attack animation. Like the other two videos, they suggest code changes (sometimes in the form of Game Genie codes) that fix the problem, if you happen to have a fondness for 6502 assembly. (I do!)

If you’d like to try NES Teenage Mutant Turtles, it’s included in the “Cowabunga Collection” that was released for Switch, Xbox X/S and Playstations 4 and 5. Fortunately, it also includes twelve much more playable titles.

Romhack Thursday: Zelda in Low Res

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

When people think about NES games, they often think of pixel art. Big chunky pixels! It’s one of the defining aesthetics of our era. The NES occupies a niche between the truly blocky graphics of the Atari VCS era and the 16-bit consoles, which don’t have a much greater resolution than the NES (since the limitations of CRT displays were a big factor), but had a much greater color depth that could help smooth things out.

But it can be interesting, visually, to try to find a middle ground between the Atari and the NES. That is where the subject of this post comes in: The Legend of Zelda Chunky Edition, a graphics hack by Zero Meaning.

There are no words for how much I love this look!

Only the graphics have changed, and just to make them more blocky, instead of the prevailing trend for remakes, which is to make them less so. (Oh also, the bright cyan of Link’s Blue Ring tunic has been darkened a bit.)

For some reason, this look suits The Legend of Zelda a lot! The greatest challenge to making it, I think is figuring out how to represent letters and numbers. You can see from the title screen above that the S, R and numeral 8 posed particular challenges, as did the copyright symbol.

There’s not a lot more to say about this one! So here are a few screenshots of Zelda, chunky style.

The Evolution of Decision and Cancel Buttons

Image from the blog in question. I presume they got it elsewhere.

ABA (who makes great tiny games BTW) linked to a Japanese blog post that goes over the traditional “decision” and “cancel” buttons on a miscellany of game systems. The link is to the Google Translated version of it; here is the original. It’s fearsomely detailed!

RetroGamerNation Covers New VIC-20 Games For 2022

The Commodore VIC-20, Commodore’s first attempt at a budget color home computer, often gets lets out of the spotlight in favor of its more capable successor, the Commodore 64. Back at release it had significantly limited RAM even for the time, only 5K, and it also had only eight colors for general use, simple sound, and no hardware sprites. Even so, it did all right in the market, but was quickly overshadowed by Commodore’s more powerful followup.

But all of these factors mean that making substantial games for it is both a more interesting challenge, and a lot more impressive when it’s done well. Youtube channel RetroGamerNation did a roundup video of interesting VIC games made in 2022. Remember, when watching these videos, the VIC had no sprites. I personally like the look of Flood. Most of these games require significant RAM expansion to run (on the VIC-20, “significant” means at least 16 kilobytes), but many people who try them out will be running them on an emulator anyway, and one of the games actually runs on an unexpanded VIC.

U Can Beat Video Games: Super Mario Bros 3

We’re brought up U Can Beat Video Games before (here’s all of the videos they’ve done to date, and here is their home page with a merch store), but this time they’ve covered Super Mario Bros. 3 in their typically completionist style, covering every level and every secret in the entire game. Sometimes they split a long game into two or even three videos, but not this time, this one video goes through the whole game, and it’s three hours and 23 minutes long! The other reason to link them this time is it’s their 100th video!

They’ve done some other interesting games since the last time we linked them, which was when they covered A Link To The Past. Some particular games they’ve done in the meantime:

Even if you don’t have an interest in seeing these games taken apart so thoroughly, many people enjoy using their videos as background while doing other things. In a Youtube environment where video makers feel encouraged to go nuts with editing and fill their footage with distracting noises, UCBVG is a model for how to create interesting and informative videos. They are great! And they have a couple of adorable dogs who appear in every video, too!
