Valkyrie Profile: a partial matching PlayStation decompilation

Valkyrie Profile decomp reconstructs parts of the Japanese Rev 1 PlayStation game as C that compiles to the original bytes. It covers the main executable and four overlays, with remaining functions retained as assembly. The author reports byte-matching outputs for all five units and warns that a build from a fresh clone may need local reference files.
