Oh man do I miss these arcade units. The unit had some pretty damn good speakers and even has one of those slots so that you can plug in your earphones and listen via the headphones and a PS2 memory card slot to save where ever you left off in the game and continue if you have the game for PS2.
As always, a quarter to play.
I played this in one of those public laundry places and played KOF 2003 and Metal Slug.
I've beaten KOF 2003 with Kyo, Leona, and Kim in case your wonder who I used.
