so you should think of supporting the files that actually come with the downloading of roms like .sfc, .md, etc download a rom from each allowed system within this nesbox and you'll see the file that comes up are not those listed in discription
SFC is one of the least rom types used, SFC stands for super famicon, i dunno where you get your stuff from but all my files are exactly as specified by the creator
actually ive gotten a few sfc downloads but there from emuparadise i now search by specified file for the games and change name title to add new games after the initial 24 slots are filled
