The cheat & copying devices below contained built-in Action Replay-style cheat codes for hundreds of SNES and Super Famicom games. When a game is loaded on these devices, their "inverse checksum" in the game's header is checked against a list of codes associated with that checksum (so, no readable game titles are stored in the BIOSes, alas.)
I've made a tool that extracts the codes from these UFO BIOSes,
compares the checksum to a list of SNES games and their checksums, and then
prints the stored list of cheat codes into HTML files for easier reading. You
can look up a game in these lists and use the X-T (X-Terminator) cheat codes
in an emulator or your own copier if it supports AR/X-T codes.
Note that SNES / SFC games sometimes store their internal game
name in an abbreviated manner, or in Japanese using Half-Width "¶Å"
characters, so you'll need to keep that in mind when reading or searching the
code lists.
