The Flipside of Gaming
Each showcase highlights the many indie games we play here on the channel, if you would like to submit a game for a future stream/video, please reach out.
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!
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!
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.
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.

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 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.
It’s a video from YouTube Channel The Retro Future with the title “Nintendo didn’t want us to know this…” which I hate. Why not just mention it’s about the difference between the Kiosk Units and retail ones? I’ve seen a hundred clickbait titles like this that have completely disappointed me.
This time though, it actually was interesting content, even if I can’t see why Nintendo would care if we knew it.
The kiosk units that were displayed in stores to demonstrate software differed from the ones you could buy in one important respect: they have a resistor in a different place on the motherboard. Without this resistor, the kiosk units will only turn on if they’re connected to power. They still have a battery, but it doesn’t appear to be used! If the resistor is removed and soldered into the location it’s at on a production unit, it seems, it’ll function normally.
Here is the video:
The generally-excellent Pringus McDingus brings us a quietly reflective moment with Arya Stark and a close friend.
John Harris: I’ve been playing a ton of Glitch revival Odd Giants, which I mentioned last month. It’s incomplete but still under development, and the original game was never complete anyway. I might write something more on it in the near future.
Josh Bycer: I just started playing Warriors of the Nile 2. it’s a tactical strategy game with roguelike elements too, a lot of ways to break the game with the right skills and every character has their own abilities and strategies to use.
Phil Nelson: I finally have been playing the recent Marvel’s Spider-Man games and Miles Morales really does kick ass as a game most of the time, but I still run into some bullshit. In a more just world we’d have a proper Spider-Man roguelike.
I like how Josh and Phil are talking about roguelikes, and I’m really into an old non-violent MMORPG with like maybe 100 players. I’ve always got to be contrary I guess.
Sil-Q is an Angband variant. Joel Ryan, aka MicroChasm, made its tileset which shows a lot of care in its creation. Sil-Q’s tiles are modular, so humanoid monsters can hold weapons, and also have strong silhouettes to aid recognition. It’s full of the kinds of concerns pixel artists have to worry about!
For this Perceptive Podcast, I spoke with one of the designers about the mobile game Dizzy Dwarves about starting their first major game development, working on mobile in today’s market, and more.
There are dozens of new indie games every month (ask blogmate Josh Bycer about that!), and it can be very difficult for any to stand out. One that has for me is Tom Astle’s Wobbledogs (Steam) a bizarre pet sim involving raising sorta-dogs in a physics system, feeding and caring for them, and mutating them as they progress through their life cycle, which involves hatching from eggs, and sometimes spinning a cocoon around themselves and mutating into a new form. Like dogs do.
Well this post is just to inform you that Wobbledogs is now on the Nintendo Switch! No one paid us for this notice-I’m just an enthusiast. That’s everything on this site-enthusiastic.
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.
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.
