# Final Fantasy VI: a three-version ROM disassembly

> Final Fantasy VI Disassembly reconstructs assembly and game data for the Japanese Super Famicom and two US SNES releases, using ca65 and ld65 to build ROMs. Its scripts extract required data from a user-provided ROM; the Japanese build fills unused regions with 0xFF and has a different CRC32 from the original.
