The X68000 port was released in 1993. The X68000 is a home computer which was only released in Japan, making this port a Japanese exclusive. It's just like the arcade version, which isn't surprising as the X68000 hardware is very similar to the CPS system.

It's unlikely you'll ever get to play this version though -the X68000 is pretty expensive to buy these days, whilst this game goes for well over $100 on eBay.
