rom-patching

A SNES cartridge image as a file rather than an address space: strips copier stubs, joins split sets, identifies a dump by digest, and rewrites the header to declare no coprocessor with the checksum recomputed across every mirror. Measured against 7,317 real cartridges.

Street Fighter Alpha 2 and Zero 2 with the S-DD1 decompression chip designed out. A plain 96 Mbit SNES ROM, no coprocessor and no mapper hardware, that runs from any flash cartridge able to hold it. Built from your own cartridge dump; no game data is distributed.
