Case study

Skies of Arcadia Legends: matching GameCube decompilation

The Skies of Arcadia Legends project reconstructs C source for the USA GameCube release and builds a byte-identical main.dol from a user-provided disc image. It tracks function-level matches, uses objdiff for comparison and documents compiler behavior affecting Sega's Ninja graphics library; some matched library code is imported with attribution.
