# Digimon World 3: matching PlayStation decompilation of three regional releases

> Digimon World 3 decomp reconstructs the PlayStation game's executable, 21 overlays and stage files as C source for European, USA and Japanese releases. The author reports that builds from the shared source match the corresponding original binaries byte for byte; the build checks its outputs against SHA-1 values stored in the repository's version configurations.
