I should have figured the Carolina Arcade Museum would have a version of Street Fighter II. Capcom updated the original Street Fighter 2 several times. Typically adding more fighters and tweaking the moves and speed of the game. This one added Cammy, T. Hawk, Fei Long, and Dee Jay to the roster.
Even after years of not playing Street Fighter 2, it was pretty easy to pick back up. I mainly played the campaign mode as Cammy White.
It still is pretty impressive how well designed and balanced Street Fighter II is. The CPU can be cheap at times, but I can see why Capcom took forever to make a real sequel to the game. If it isn't broke, don't try to fix it.
