I have many roms for NeoGeo. Im getting some roms for NeoGeo CD. I see there are some roms that are the same, like PulStar for NeoGeo and PulStar for NeoGeo CD. I am wondering, which one would be better? Graphics wise? Another duplicate game ive seen is Metal Slug 2, would the NeoGeo be better than the NeoGeo CD?
