@lostless Thanks for the link, it does seem like the problem I'm having. I'll have to try the patch that was mentioned at the end of the thread and see how it goes. Unfortunately my build is in a old NES case with the two original controller always plugged in and inaccessible without opening up the entire case. So if I can't figure this out I guess my only remedy is to open the case and unplug the NES controllers each time I want to use the SNES ones. Here's hoping that isn't what I have to do.
