• Added jump spark effect • Added landing dust effect I used two sprites for the dust; they use the same spritesheet but are horizontally mirrored, allowing me to adjust the spacing for each character. #dragonball #sega #megadrive #SGDK

I have successfully reverse engineered and decompiled Snood for the GBA (2001), a game originally created by @GCDaveDobson over 25 years ago, entirely driven by AI. Every byte matches (SHA-256). I used Opus, Codex, and dozens of parallel DeepSeek V4.1 agents to attack different parts of the codebase. The first step was finding the compiler, where I sent off some agents, and they discovered it was agbcc, the GCC 2.95 compiler from Nintendo's GBA SDK, and verified it by recompiling standard library functions like memcpy and getting byte identical output to the ROM. For the first week or so, matching was stuck at 3% as I had no idea what I was doing. Then one afternoon, I experimented with agent swarms and went from 7% to 81% in about 5 hours. I ran over 20 DeepSeek agents in parallel in multiple waves, each AI assigned its own function in its own sandbox, so they never stepped on each other's work. The bigger AIs merged each result only after re-verifying their work, picking and choosing what was best. The last 19% took several more days, and the last 300 bytes were very difficult compiler forensics. This work is particularly suited for agentic workflows as the reward is easily verifiable (matching rom percentages). Why Snood? I have a faint memory of playing this game at around 3 years old. I also remember hearing the video game soundtrack and wondering "How did they fit that in the cartridge?" Well now I have my answer, they used the GBA's four built-in sound channels in a sort of midi-like way to generate songs on the fly. Only the sound effects are real samples, 8-bit audio at about 11 kHz. I also wanted to choose a game that was relatively obscure, had little info, as Pokemon has been analyzed to death (and I didn't grow up playing Pokemon!) I don't have an accurate number on the cost, but it was around 4-5 billion tokens. I do feel a bit strange, as now I was no longer tell AI what to do, I was telling AI what to tell AI what to do! The knowledge I gained from this project is mostly high level about how to coordinate agents, rather than technical details (though, now that I have the code, I can ask any question and figure it out). What would've taken a team of hobbyists years took me about two weeks of on and off work. I think we're about to see a lot of forgotten technology and code get preserved, which, in the face of AI writing more and more code every day, is kinda amazing in my eyes. The future is very bright for technological preservation efforts. If you're interested in the code, let me know below. Enjoy the cutesy explanation video!

@ZekeFreek For Metroid I would recommend the hackrom with map, for Metroid 2 the hackrom with colors. Then the remakes.

Our real Mickey Magic demo is here! A clip plus the actual #SNES ROM to download and try for yourself. This is a first rough pass with backgrounds only, so it's not final yet: archive.org/details/mickey… #SNESdev #SuperNintendo #16bit #pixelart #retrogaming #homebrew #indiedev

This is Super Metroid on the SA-1 chip. No music yet, but SFX plays, opening works. Impressive that even with SFX only the opening is dark and the ambience hits hard. Been working the entire weekend on this (among with SimCity multi-languages). Hope to share more scenes soon.

Effulgence RPG 1.0 is out now! After more than two years of solo development, the full game is finally here. I created its ASCII visuals by hand and programmed the game myself. Steam: store.steampowered.com/app/3302080/Ef… #indiegame #rpg #ascii

Es bastante probable que Majora's también tenga su remake, pero creo que le hace más falta (y que tmb vendrá) a Super Mario 64 #Nintendo

This is awesome, impressive detail for a 1995 game. I'm sure this has some hidden psychological effect to reduce fatigue and improve replay value

Mais uma descoberta aleatória: Em Yoshi's Island, a cada vez que você entra em uma fase, o cenário fica levemente diferente. Note como, de um print pro outro, os cipós possuem dobras diferentes, folhas mudam de lugar e os detalhes da lama mudam de posição.

30 seconds of gameplay from my upcoming indie game.

@Davo64M3 I use and abuse save states, no shame, life is short when you are in your 40s.

I created a small app a few days back that started old-school HD whirring noises and clicks when my SSD started being really busy. Sometimes it's it's nice to know that your computer is running slowly because something is eating up IO. Yes it could just be visual but I ignore that normally.

First VERY ROUGH 60fps Starfox native PC port...shoutout to @HackerVilela for suggesting I do this! (AI Assisted)

This is a a 24-bit pixel art remake of the 1992 Amiga shoot 'em up Apidya, 33 years in the making. This is Apidya' Special and it's out today, how good does this look?

I left only Crash and the level. It runs at around 30-55 FPS. That part is already well solved. I still need to simplify the rest of the project, which has unnecessary complexity. #whisk3d #crashbandicoot #nokia #symbian #ps1
