Here's what I'm bringing:
Final Fight
Simpsons
Battletoads
Cadash
Aliens
Captain America and the Avengers
Spider-Man
TMNT
Sunset Riders
I'm leaving a few behind, mainly because they have issues running on the Sigma, for some reason: Magic Sword, Knights of the Round, Sailor Moon, and a legit JP X-Men.
Also, I used to run an Atomiswave setup but, that got a little wonky because it needed proprietary control pads wired up...not to mention holding in button 5 for more than 3 seconds made the system think it was having a coin error (resets the system).
