yeah alot of the files have the exact same filesize in bytes even though the content is different, the only way i could see is to caclulate a crc value but this would slow the emulator down, or calculate the value at some hex location in the file, so it could be atrac-legnth-hexvalue.at3 - but this isnt without problems since some files are really small..
on second though usually jpcsp has to copy the at3 file, so if it calculates a crc/md5/sha1 instead or while it copys maybe there wouldn't be much of a slowdown usually the files are small too like 4-10k.
here are just a few at3 files from cc (all identical filesize in bytes :X)
