# Bubsy 3D: a work-in-progress matching decompilation of the USA executable

> Bubsy 3D reconstructs C for the USA game's SLUS_001.10 executable and compares compiled functions with the original bytes. Its code map separates exact matches from fuzzy candidates and documents unresolved executable regions.
