# Super Smash Bros. Brawl: an early matching Wii decompilation > A work-in-progress matching decompilation of Super Smash Bros. Brawl that targets the USA Rev 2 Wii release (RSBE01_02), splitting main.dol and 126 REL modules from a user-supplied disc image and checking the rebuilt binaries against stored SHA-1 values. objdiff compares objects during development, and six other regional revisions are listed but commented out of the supported set. decomp.dev reported 1.27% of code matched at the reviewed commit. - Type: Case study - Targets: Game - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-19 - Added to the catalog: 2026-10-28 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/smash-bros-brawl-decomp-case/index.md) ## Requirements & limits - README lists one supported version, RSBE01_02 (USA Rev 2), with the Japan, USA Rev 1, PAL and Korea revisions commented out; configure.py names all seven, but only RSBE01_02 has a configuration and CI builds only it. The output is a Wii main.dol and REL set, not a PC port. - Copy your own disc image to orig/RSBE01_02; ISO (GCM), RVZ, WIA, WBFS, CISO, NFS, GCZ and TGC images are accepted. README says the repository contains no game assets or assembly: decomp-toolkit splits the DOL and RELs using committed per-module symbol and split tables, and extracts one embedded binary (HomeBtnIcon) from the DOL locally. Game headers come from the BrawlHeaders submodule (Sammi-Husky/BrawlHeaders), which README says to initialize before building. - Builds need Python and ninja on Windows (native tooling recommended), macOS (with wine-crossover) or Linux (an automatically downloaded wibo on x86, Wine elsewhere). configure.py pins decomp-toolkit v1.7.5, objdiff v3.4.4, binutils 2.42-1, sjiswrap v1.2.2, wibo 1.0.0 and the 20250812 compiler bundle, compiling and linking with Metrowerks GC/3.0a5.2. - Objects marked Matching (184 in configure.py; 20 remain NonMatching) are compiled from source and the rest come from the split originals; the default ninja target checks main.dol and the RELs against config/RSBE01_02/build.sha1 before reporting progress. CI builds RSBE01_02 in a container that supplies the disc files and compilers and uploads a progress report. decomp.dev’s report for the pinned commit lists 201,252 of 15,833,548 code bytes (1.27%) and 2,504 of 92,523 functions matched, with 516 of 4,415 units complete. - The repository carries CC0-1.0; Nintendo’s game, disc contents and the downloaded compilers fall outside that dedication, and the BrawlHeaders submodule declares no license on GitHub. ## Primary sources 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. ## More in Games - [Super Smash Bros.
