There are a few SNK pachislos out there. The Metal Slug one is really cool. They seem very hard to find, though. Maybe the KOF machines are easier to come by, I’ve never really seriously looked into those. Let us know what you think of the KOF machine.
I have an older model pachislo, and its fun in short bursts, but I would like to sell it and get one that has a videogame theme (there are a couple cool Biohazard machines out there).
