This works great if it were not for 1 issue. When you play some of these games such as Super Mario the keys should be changed for better gameplay and comfort. Can you please write this so that you can config the keys to your liking? Or can you right them so that nes games keys are X=A and A=B. And for the SNES needs to be A=B, B=A, X=Y, Y=X. Me and many of other retro gamers that I know all agree on this matter. All thought This is a GREAT Emulation set up this is the only issue. Thank you for your work on this and please do not take this in a attack in any way. I just really hope that you can make the changes or have it set up for key config. Thank you.
