The ROM has a non-standard pinout and I dumped it but it was a fluke. I still have no idea how it came out mostly ok ![](//www.mameworld.info/ubbthreads/images/graemlins/biggrin.gif) To fix it I'd need another Atomiswave mobo and some time to figure out what's going on there. Probably not going to happen so this is as good as it gets.
