I have Snes9x v1.56.1 on Windows 10 and am using a Tomee USB to SNES controller adapter. I set up all the input configurations for the SNES controller(which worked) but I can't hit two buttons at once. You can see both buttons are being pushed and flashing back and forth really quickly between them. The problem doesn't happen if I use keyboard configuration. Anyone else have any luck fixing this problem?
