In the next few days I'm planning on acquiring a NeoGeo Pocket color. I've already got Samurai Showdown! 2, but I'm looking for other good games to enjoy for quite a while. Aside from SNKvsCapcom MotM which I will definately get when I have the chance.
I've gotten a bit tired of emulating this, so I decided to get the hardware lol.
NGPC Games
Rockman Power Battle/Fighters maybe? There the Metal Slug games... Maybe King of Fighters? I'm not familiar with NGPC so I wouldn't know too many titles. Ofcourse I don't think the system even has that many titles. You could check the GameFaqs listing of games.
