There is no other way that I know of except to download the .36 older version of MAME for PC and test the roms on it. That being said, might as well just test them on MAMECE on your PPC. There are utilities called Clrmame and Romcenter that are suppose to rollback rom sets but many cannot be reverted however they can tell you if the rom is a legit version of the one you want. I can't figure either one of these utilities out so you are on your own.
