@xwons I just came across this thread on google, registered to this forum just to confirm xwon's solution fixed this problem for me. No more troublesome multitap snes games! Thank you for taking the time to respond to this thread with the answer.

@brad2600 no i think they should be. But its a bit of a process to do it. I wont be back home until monday to get on my computer, but i will try to remember to post on how to do it. You have to make a config for each game so it takes a little work to do.
