Is the PC version (DOS) a port of the SEGA Saturn or the PSX version? And does it support splitscreen multiplayer? PSX/SAT supported up to 8 (!) player on one single screen! I read on some old tests, only 4 are available on PC (DOS).

OK, I own the game now and I think, it's based on the PSX version, but I'm not quite sure. It supports SVGA and up to (only) 4 player.
