snowboardkids2-decomp

Reverse-engineer N64 assembly into matching C code

Decompiles Nintendo 64 assembly from Snowboard Kids 2 into C code that compiles to a byte-identical ROM. Eliminates guesswork in matching functions, renaming symbols, converting asset arrays, and fixing BSS and data segment layouts. Provides build-and-verify scripts, diff utilities, and microcode references so each change is validated against the original ROM checksum.

npx skills add cdlewis/snowboardkids2-decomp --all -g -y

Available:

Tells the agent how to bootstrap a decompilation environment for a function, iterate on C code until it matches the target assembly, integrate the result, and verify the full ROM build before stopping.

Frequently Asked Questions

FAQPage Schema

How to install snowboardkids2-decomp?▼

Run `npx skills add cdlewis/snowboardkids2-decomp --all -g -y` in your terminal to install all skills in this suite globally.

What is a matching decompilation project?▼

It is a reverse-engineering effort to write C code that compiles into the exact same assembly as the original game ROM, verified by checksum.

How do I decompile an N64 function to C?▼

The skills guide the agent to spin up a per-function environment, compile candidate C files, diff them against the target assembly, and iterate until the match reaches 100%.

Can it handle F3DEX2 and S2DEX microcode?▼

Yes. A dedicated skill identifies display list commands, disassembles them, and rewrites them with the correct gbi.h or gs2dex.h macros.

Do I need to own the game to use this project?▼

Yes. The repository contains no game assets, so you must supply your own Snowboard Kids 2 ROM to extract and rebuild.
