# Digimon World 2: a matching PlayStation decompilation

> Digimon World 2 Decompilation reconstructs the USA PlayStation game's main executable and seven stage overlays as C source. The build compiles with a period PSX GCC toolchain, links each component, and compares its SHA-1 against files from the user's disc. The author reports byte-identical rebuilds and 1,088 matched game functions.
