most of the time they will NOT work.
while the file names might be the same, the size can differ greatly.. an US game ripped with a PAL rip kit might not fit on a CDR anymore. also, many pal games contain multiple language options, US games don't.. and especially the german kits will remove all but german, but in the US game, there aren't other languages in the first place, so it will fail to find the files.
