Street Fighter III 2nd Impact: a matching CPS3 program decompilation

Street Fighter III 2nd Impact reconstructs the CPS3 arcade program as C and SH-2 assembly. The build uses the Hitachi SHC toolchain, reads graphics pattern tables from the user's ROM set, checks the linked program against the arcade program's SHA-1, and compares rebuilt SIMM chips with the supplied ROM chips. The byte-match figures are the author's report.
