That would be pretty cool. Crystalis was such a good game.
OT: I think the reason they are doing this though is so they can get a cut of the system sales (obviously). What I mean is there are several outlets that are consolizing the arcade units and selling them for big bucks to get them in collector's homes, and SNK want's a piece of that pie. So, solution is simple - release a handheld that you can play on the go, or attach it to a TV and use an old school controller to get the full NeoGeo console experience at a fraction of the price those modders are charging. Some of those consolized Neos are upwards of $600. I still don't know how they're handling games though outside of that inital batch.
