About

An in-progress decompilation of 1080 Snowboarding for the N64, which the README says is mostly driven by Claude. The build is ROM-exact: make produces a ROM byte-identical to the original, and twenty segments are being decompiled. A 2026-09-12 snapshot lists 2,428 of 3,305 functions matched, 38.22% of code bytes matched and 85.04% fuzzy credit.

Getting started

You need your own 1080 Snowboarding (USA) ROM, MIPS binutils, Python 3 and the IDO 7.1 compiler. Put the ROM in the repo, run the setup step to extract assets from it, then run make. Extracted asset files are not committed and are regenerated from your local ROM.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (N64 version).
