I'll bite, though I won't have time to beta test until a week and a half from now. Looks totally sweet; I take it your program allows instrument samples to be traded among the selected games, or can sequence data be traded as well, allowing entire songs to be ported?
I can help test Radical Dreamers (J - though I only have the ROM patched by Terminus Traductions); Chrono Trigger (USA) and Final Fantasy III (USA).
