Rebuild old game code from games you own with agents
Developer i12bp8 built decomp.wtf, where coding agents turn retro game code back into readable code; the guide shows one Nintendo 64 piece matching exactly, with no overall results.
Done with Claude Code
What they did
Developer i12bp8 built decomp.wtf, a tool that lets coding agents like Claude Code help rebuild readable source code from old games. It splits a Nintendo 64 game file into small pieces. Each agent takes one piece, with its machine code, related data, a rough draft and notes from earlier tries. Every attempt is rebuilt with the game's original tools and compared to the real game, and any mismatch is sent back.
How it went
The project's guide shows one small piece written by an agent that rebuilds into exactly the original Nintendo 64 code. No overall results are given.
Worth knowing
The author shut the project down because much of the game-restoration community opposes AI doing this work. They ask people to use it only on games they own, not share the code, and respect projects that refuse AI help.
Try it yourself with Claude Code
Decompile my game at [path to ROM I own]. First confirm it is my own copy, then import it and open the live view so I can watch. Work one function at a time and only accept C that compiles to the exact original bytes with the game's original compiler. Keep a log of matched and unmatched functions. Do not share the output or open pull requests to any public project; show me the commits and wait for my review first.Swap the highlighted [parts] for your own details.
