Armored Core: matching PS1 executable and overlay reconstruction

Armored Core Decompilation reconstructs C source for the USA PlayStation release of Armored Core. It splits the executable and FDAT.T code overlays, compiles recovered functions with a period PsyQ toolchain, and compares rebuilt files and functions against a user-supplied disc; the author reports partial function matching.
