Actually, I'd like to add and change my previous statement a bit. There are two games, Variable Geo Max and Variable Geo Custom developed by Ton Tan Nerw, an actual fotware company. Both games are distributed on CD-ROMs. Even though my my previous comment about them being free, they're still not hard to find. Try looking through abandonware sites. V.G. Custom is a semi-sequel to Max which adds a "super super combo", the ability to block and attack at the same time, voice acting and a hidden character. Both appeared first on the PC-9801. The PC port has these aforementioned enhancments. Still, based on the reviews, people like Max more than Custom, saying that Custom has choppy animation. Go figure.
