The otherwise saintly and beloved MAME Team doesn't seem to give a rat's ass about game recording. They don't test it, don't fix it, and sure the hell don't list any reported recording problems. May speed up new versions but it's inconvenient as hell for MARP :)(posted 9616 days ago)NOT ONE GAME, NOT EVEN BLASTED CARNIVAL WHICH HAS BEEN BROKEN IN ALL VERSIONS BUT 33B4 HAS A WARNING IN IT SPORTSDUDE!!!
Sorry about the overreaction, but you really do have to test first.
