Final Fantasy IX: matching US PlayStation decompilation

ff9-decomp reconstructs the US PlayStation Final Fantasy IX boot executable and code overlays as C that the author reports compiles to byte-identical binaries. The workflow extracts data from four user-owned discs, while PsyQ SDK code stays in assembly and separate equivalent C supports port work.
