The “No Fire” Trick in Galaga

Arcade Galaga has an interesting bug that’s been known of for a long time, that can be taken advantage of to cause the enemies to stop firing. The inner workings of the bug are explained on its page on the website Computer Archeology, but here it is in brief: on the first level, if you leave the bugs at the far left or right sides of the formation alive and wait long enough, 10 to 15 minutes, just surviving their attacks, then eventually the enemies will stop firing all together, and will never fire again for the rest of the game.

Why does this happen? Galaga reserves eight hardware sprites for the shots of the enemy bugs. Galaga’s graphics hardware has no way to disable the displaying of a sprite, so if something isn’t supposed to be visible it’s kept off screen, at horizontal coordinate zero. A shot sprite at that coordinate is never updated, and never moves. This is in addition to the game’s internal records of which shots are in use. When a bug wants to fire a shot, the game looks at which shots are available, and if one isn’t in use, it puts it at the proper place, and sets its velocity (X and Y deltas). From then until it leaves the screen, it’ll be updated every frame. When it is detected as having gone off-screen, it’ll be marked as out of play, and its X coordinate will be set to 0. Shots at X=0 are never updated.

The problem is, it’s possible for bugs to fire shots while they are at X position 0. This happens most commonly when bugs at the far left and right extremes of the board attack. The shot is marked as in-use, but it’ll never be updated, and so it’ll never be cleaned up and set back to be available for firing. When all eight possible shots are in this limbo, the bugs can’t fire any more. The machine resets the shots at the end of a game, so the problem won’t affect subsequent plays.

Ben Golden Diamond performed the trick in a Youtube video, and he manages to get it to happen in around seven minutes. He doesn’t explain the precise criteria for doing the trick, but his description will still work, it just has unnecessary steps. It will work on any level, but it’s easiest to do on the first. In the video, sometimes the bugs fire wraparound shots from off-screen. That’s a good indication that the bugs are sometimes firing from the 0 coordinate.

Keep in mind, performing the trick on purpose will disqualify a score for world records. The scoreboard on a local Galaga machine probably won’t care, though.

More From Displaced Gamers on Dr. Jekyll and Mr Hyde

We presented Displaced Gamers’/Behind the Code’s video on the jankiness of kusoge disgrace Dr. Jekyll and Mr. Hyde back on Saturday. They did another video on that game, that delves into why the game’s frame rate is so inconsistent. In summary, its engine throttles its framerate in a terrible way, using long delay loops. It’s a pretty awful idea! It’s 19 1/2 minutes long. The video claims it’s even geekier than their first video on the game, but I think it’s actually slightly less technical, at least it doesn’t fill the screen with as much 6502 assembly code.

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!

Behind the Code: Dr Jekyll and Mr. Hyde

For some reason there’s been a lot of Youtube videos lately that fit our eclectic purview, so here’s a code-heavy dive into infamous NES disasterpiece Dr. Jekyll and Mr. Hyde.

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….

Mega Man’s Score System

Looks like we’re on another Youtube binge, ayup ayup. This time it’s another hopeful video constructor asking us to consider the oddity of the score system in the original Mega Man (a.k.a. Rockman).

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.

Pac-Man in Three Patterns

PacStrats on Youtube has a video that gives three patterns that will take a casual player all the way to the kill screen at level 256.

I say casual because this doesn’t attempt to produce a “perfect” game, of 3,333,360 points. This is because it doesn’t attempt to eat all four ghosts on every Energizer while that is possible. It actually ignores the ghosts when they’re vulnerable. There are patterns for that on PacStrats too, but you’re not going to be able to do it by memorizing just three patterns. You can really push your personal limits, and that of your free time, trying to get better at video games, and most of us have a point where we have to say that’s enough, and then go and read a book/buy groceries/have sex/something else. The three patterns in the video below are a nice middle ground.

It isn’t easy to devise a Pac-Man patterns, and it’s much harder to come up with a small number of patterns that cover all the levels. Patterns work because the movement of the ghosts is completely deterministic, depending on how Pac-Man moves. If you can move Pac-Man with frame-perfect accuracy, then the ghosts will oblige you by always responding in the same ways. The frame-perfect requirement is eased up a lot by the nature of Pac-Man’s motion. So long as you don’t reverse directions or delay, Pac-Man can only change direction at intersections. So long as you have the joystick, or whatever ludicrous controller setup you’re using, pressed in the direction you want to go next three frames ahead of the turn, your gluttinous circle’s progress will be on track for that pattern.

So, if you try to perform a pattern and it doesn’t work, what went wrong? Most commonly it’s because you hesitated at some point, failing to make a turn at least three frames in advance. Sometimes that’ll be okay, but two of the ghosts, Pink (Speedy/Pinky) and Blue (Bashful/Inky) use the direction that Pac-Man is facing in their AI calculations, and that can change much more rapidly compared to his location in the maze. Even being a single frame off in your timing can produce a situation where Pac-Man will be facing a direction that will cause them to take a different path at a choice. Also, some of the motion of the ghosts is determined by the amount of time that’s elapsed in the current level, and if Pac-Man’s in a subtly wrong position then it can be disastrous later on.

The periods over which the patterns are good are the first four levels (Cherry to second Orange), levels 5 through 20 (first Apple through to 8th Key) and from 21 onward (9th Key to the kill screen). The actions of the ghosts are not the same throughout the run of each pattern. The second pattern, in particular, works over so many levels mostly because its creator, through trial and error, happened upon a pattern that’s good for so much of the game. Because the travels of the ghosts will be different on different levels, it’s important not to get spooked because they are moving differently than they did on previous levels. So long as you move Pac-Man through the patterns assuredly, without delay, and at least three frames in advance, then he’ll clear the boards in succession for as long as you care to keep going, until level 256, where Pac-Man’s All-You-Can-Eat buffet closes its doors.

Unfortunately, PacStrats has made their pattern video non-embedable, so if you want to see these patterns in action you’ll have to click through to the video’s Youtube page.

Sundry Sunday: From AGDQ, A Dog Replaces R.O.B. in Gyromite

Sundry Sunday is our weekly feature of fun gaming culture finds and videos, from across the years and even decades.

This week’s fun video isn’t decades old, in fact it’s from just a few days ago, from AGDQ.

The NES title Gyromite, a.k.a. Robot Gyro, is a very interesting game from a design standpoint, possibly more interesting than it is to actually play (although I think its music is very catchy). It’s never been rereleased by Nintendo, for the probable reason that it relies on the accessory R.O.B. to play.

R.O.B: It’s not just that funky Smash Bros. character! (Image from Wikipedia, taken by Evan-Amos.)

R.O.B. was a motorized accessory that activated servos in its arms depending on light signals sent to it from the screen. No cords went from R.O.B. to the NES. It used photoreceptors in its “eyes” to detect the screen signals, which were ultimately caused by player input on the controller. A fairly roundabout means of control, honestly.

Only two official R.O.B. games were made, and Gyromite (Going by its Japanese name “Robot Gyro” according to the title screen) used the “gyro” accessory for play. A platform is placed in front of R.O.B., on which you place the controller for Player 2.

On the controller is a device that spins the “gyros,” colored weighted tops. By manipulating the arms with action on Player 1’s controller, making them swing around and opening and closing the claws at the right time, you can cause R.O.B. to lift the spinning gyros from their platform, then set them down on the NES controller’s buttons. In the game, this caused colored pillars to rise or fall according to the control signals.

R.O.B. with gyro setup. Image from the blog Nerdly Pleasures.

While manipulating all of this, you also have to watch out for the action of the game itself. Gyromite is a simple platformer, but one without a jump button. The difficulty comes from having to essentially play two games at once, the platforming on screen and manipulating R.O.B. to position pillars in the right places in space and time.

R.O.B.’s motions are not simple to command either. It takes time for the arms to pivot between their destinations, time that must be accounted for in the on-screen action, and while the tops spin for quite a while they will eventually have to be collected and set back on their pedestals so they can be spun back up to full speed, or else they’ll topple over on the button. This doesn’t produce a failure state in the game. It’s just left to you to pick the top up yourself and put it back on its stand to be spun again. R.O.B. isn’t capable of such feats of dexterity.

There’s a lot more to say about R.O.B., and how it was mostly distributed as part of the Nintendo Entertainment System’s “Deluxe Set” in the U.S., the more expensive version that didn’t come with Super Mario Bros. Instead of that, let’s talk about how, due to the fact that R.O.B. is just a fancy-shmancy way to press controller buttons, that you can replace it entirely with some other mechanism, or indeed, even animal.

That’s what happened Wednesday at AGDQ, where Peanut Butter the Dog, with coaching from JSR_, left R.O.B. gathering dust in the closet as they played through Gyromite Game B.

They didn’t make it all the way without running out of lives, but they picked back up and kept going. And that doesn’t detract at all from Peanut Butter’s skills, or amazing doggy focus. They are intent on reading those hand signals and getting those tasty treats. So while they didn’t earn a world record, for “Dog playing Gyromite Game B,” their accomplishment is of definite note.

There are around four minutes of introductions at the start of the video, so if you want to jump right in to the run, begin here.

The 10th-Key NES Pac-Man Scatter Bug

I already shown it off on Mastodon, but I’m so pleased with getting this bug on video that I’m re-reporting it here! First, though, some background.

Still the definitive resource on the design internals of Pac-Man.

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.

Figuring Out Yars’ Revenge Code From Its Graphics

What is Set Side B about? We talk about old arcade and NES games, Nintendo things, weird gaming-related videos, ancient MMORPGs, and other weird and idiosyncratic things largely as they inspire us, much as how beta particles and gamma rays inspire random atoms as they pass through them, causing mutations and cancers along the way. (Alpha particles are too bulky to pass through, but that’s really just highly energetic ionized helium anyway!)

One foundational aspect of what we choose to highlight, though, are the extremely technical things, and wow, in that regard today’s link delivers. The brilliant Youtube channel Retro Game Mechanics Explained, which appears here semi-frequently, did a video on the Atari VCS/2600 game Yars’ Revenge that has to be seen to be believed, if not always quite understood.

It’s been random floating game knowledge for a while that the “Neutral Zone” area in Yars’, a flashing and coruscating band of lights that serves as something of a safe zone for the player’s bug, was the direct result of reading the game’s own code out of memory translated and displayed on screen. After all, machine language opcodes are just data, and the VCS has such a hugely limited address space that any reuse of that data is helpful.

RGME went through the graphics displayed on-screen and tried to see how much of the game’s code could be pieced together using it. The answer was, a fair bit, but not all. The process is really the most interesting part about it. Here it is:

Of particular note, the top comment on the video (because it got pinned there by RGME) is from Yars’ Revenge creator Howard Scott Warshaw himself!

In passing, let me just comment for a moment on what a weird phenomenon Yars’ Revenge is? It’s the best-selling original (non-port or license) piece of software for the old Atari. It’s such a weird artifact. It’s not a traditional style of game design. It’s got atmosphere, and strangely evocative sound. And it has that odd easter egg that can just outright end your game if you’re not careful. It really feels like an object of its time, that couldn’t have both come about and be as popular as it was in any other age. It didn’t inspire many imitators. But, it did come about, and it was popular, and I’m glad that’s true.

I watch this video and I wonder that it seems targeted so directly at me personally, that I wonder if anyone else might enjoy it at all. But then I look at its view count and see it’s approaching 200 thousand in around two weeks, so someone else out there must like it too. So: please watch the video, if you care about bits and bytes, opcodes and operands, and Exclusive-Ors. Or want to learn about those things. If neither is true for you, I’m sure there’ll be something more to your tastes tomorrow.

The Original Neverwinter Nights

The World Wide Web is now over thirty years old. In that time, more content has vanished from it than remains now, but some of it can still be dredged up from the shadowy archives of the Wayback Machine. This is the latest chapter in our never-ending search to find the cool gaming stuff that time forgot….

I feel sometimes like the kid from The Sixth Sense. That reference probably dates me to an extent, it’s from 1999 which feels like practically yesterday. It’s pretty recent as my references go: I know who Kojak was, and remember M*A*S*H.

I feel like that kid because when I look over the internet, sometimes I see ghosts. The shades of dead games. When something disappears from the web, it’s really gone, there is no corpse and its server leaves practically no trace of its existence. But sometimes signs can be found, like archived client uploads, broken hyperlinks, site snapshots on the Internet Archive, or still-active fansites.

One of those ghosts that flickers into my hazy vision sometimes is the original Neverwinter Nights. Not the Bioware game by that name, which really has very little to do with it. The first Neverwinter Nights was a SSI-produced MMORPG on America On-Line, that lasted from 1991 to 1997, a contemporary of Island of Kesmai, and of WorldsAway,which I’ve brought up here before.

NWN might have been a MMORPG, but it was also a MS-DOS game, and it ran on a modified version of SSI’s Gold Box engine, and (I presume) used the 2nd Edition D&D ruleset. That may have been what doomed it in the long run, for the license expired, and AOL, TSR and SSI couldn’t reach an agreement that would allow the game to continue. It is worthy of note that of those three companies, two don’t exist now, and the remaining one is nowadays nearly a ghost itself. I’m not going to say it happened because they couldn’t reach an agreement on continuing NWN, in fact it probably wasn’t, but it’s a little comforting to think it might have contributed. Two things that are equally disposable, it seems, are old MMORPGs and the hide-bound corporations that ran them.

There is a fansite devoted to the AOL Neverwinter Nights, apparently continuous in existence from the days the game was live. It hosts a fan recreation called Neverwinter Nights Offline, which is not an exact recreation of the original but recreates a large portion. Of course, without other human players inhabiting the game’s world, it’s nowhere near the same. It runs in DOS, so Dosbox might be of some use to you.

There is also ForgottenWorld (no relation to Capcom’s arcade game), a fan-made recreation of Neverwinter Nights. The note on the fansite dates to 2004, but ForgottenWorld still survives, and even has a Discord. I haven’t tried it myself yet, nor the offline version of NWN linked above. That’s because I see ghosts like these all the time, and I cannot devote the time or energy to any of them that they truly deserve. But maybe, you can.

On Neverwinter Nights Offline, there is a series of Youtube videos where aulddragon plays it for four hours. The first video in the sequence follows. Check out that Gold Box combat style!

The Many Revivals of Toontown Online

planet clue on Youtube posted a roundup of the many recreations of Disney’s defunct MMORPG Toontown Online, which range from strict remakes to expanded projects that add a considerable number of features to the original.

Fan-made MMORPG recreations and revivals, sadly, never manage to gain even a small fraction of the users of the originals. This is for several reasons, particularly the lack of ad budget, and a desire to stay partially under the radar, necessary to avoid legal reprisals from the original publisher–which, I remind you, in this case is Disney, the 2,000 lb. gorilla-mouse of lawsuits.

These F2P MMOs are a large part of many people’s childhoods though, and it’s inevitable that there be community interest in reviving them, if just to be able to visit old virtual stomping grounds once again. The people that I shed a tear for are those who played old Compuserve and AOL-era MMOs like Island of Kesmai (which exists in two fan-run forms, LOKFreedom and Lands of Kes) and, particularly, the original AOL-based Neverwinter Nights. But more on that tomorrow….

I think it’s possible that Disney will come to realize how many people have fond memories of Toontown Online, and also Club Penguin (which also has a fan revival), and bring them back after some time. They are not insensible to bringing in yet another revenue stream, and they’ve been open to revivals of other old video game properties of theirs like Ducktales Remastered. If that happens though, will they then launch their legal-nuclear missiles at the many fan remakes of Toontown Online? It remains to be seen.

720 Degrees Hints and Tips

Following on from the Defender tip video I linked, here’s a high-level tip video for a “radically” different game, Atari Games’ wonderful yet challenging arcade skateboard adventure 720°.

It’s really different, not just from space shooter games, but from just about everything else, even from other skateboarding games. In some ways it’s much like an early, 2D version of a Tony Hawk game, with an open world to explore between events called Skate City. But it also has a bit more going on than that: you have to earn points in Skate City doing tricks in order to earn Tickets, which allow you access to the four parks at the edges of the big isometric area, and you can earn money by doing well in the events to earn gear upgrades for your skater. Yes, there’s an equipment system in this 1986 arcade game!

Exploring Skate City isn’t a laid-back experience, however. It’s timed, and when that expires a now-iconic voice proclaims SKATE OR DIE, announcing the arrival of the killer skateboarder-hating bees, which get angrier, faster, and more Warner Bros. cartoon peril-like as further time elapses.

The only way to “die” in 720° is to be caught by the bees, all other defeats and injuries are harmless, but the bees still end lots of games: on default settings, you need 10,000 points to earn each Ticket, which is quite a lot! You are spotted a Ticket when you continue, but it’s not a gift or purchase, but a loan: the game will increase the points needed for the following Ticket by 10,000 when it happens, so you’ll have to score even more points to make it to the following Ticket. But lest you think this is a naked ploy by Atari to force players to credit-feed to see the later parks, you only get two of those continues! It’s best to think of continues as failsafes, in case you have a Ticket but get stung before you make it to a park.

720° is particularly interesting because of its unique joystick. It’s a standard 8-way stick, but its mechanism forces it to point in one direction at all times, so instead of pushing where you want to go, you spin it. The video contains a lot of that spinning. 720° is a very physical game because of it. In most games, arcade or otherwise, the controls could be considered just a way to communicate your intentions to the game, and missed inputs where you had intended to act feel like a betrayal by the hardware, but games like 720°, and Namco’s Alpine Racer, and Atari Game’s Marble Madness, the controls feel like an intrinsic part of the fun.

In the first class of these games, a brain interface might possibly be welcome for getting the controllers out of the way and removing any question of what your intent was, but 720° would be an entirely different experience that way. Physical execution is essential to the experience. It’s also a different game when played in emulation, because of it.

720° was designed by one of Atari Games’ most successful teams, John Salwitz and Dave Ralston, who also designed Paperboy, Cyberball, and my favorite of all of Atari’s output, probably my favorite arcade game of all: Rampart. Sadly, it looks like Rampart, while successful (at least judging by how many ports it got), was the title that marked their departure from Atari Games.

So relax for half an hour, or however much of it you can stand, and watch a 720° master demonstrate how to win over this uniquely challenging arcade game, on a physical cabinet no less. It’s a world where you earn 500 points from knocking over a bodybuilder, and isn’t that a place we’d all like to live in?
