The PC port's nice, yeah, but it's not... Convenient. You need an older MMX processor (I'm pretty sure it doesn't run on P4 or Athlon XP processors), adapters for twinsticks, and even then, it doesn't run at a full 60fps. Still a hell of a lot better than the Saturn version.
Actually, there was a hardware-accellerated version of the PC port that was designed solely for a certain type of video adapter. Sadly, the video adapter only came on-board, not in card form, and I haven't gotten it to run on any other card. I'd imagine that would be an almost-perfect port. ...I'd also kill to find that motherboard.
