While working through my pile of Hyper Olympic '84 pcbs today i realised that the rom arrangement is different to Mame... whether the code is different or not i don't know, i'll leave that to the mame guys to figure out. All the roms are noted with a 'D' instead of mame which shows 'C'. Konami were fond of duplicating 99% of the roms across sets, but changing all of the naming. After tracking a bunch of tough problems and replacing way too many chips that didn't fix the fault, the pcb was 99% there... there were just a few bits of garbage left on the pummel horse round in the game character... turned out to be a bad rom at J19! all fixed.
