Hi, I am building a table top arcade cabinet for a christmas present and I am currently running into some issues with the controls. I have configured Adafruit's retrogame and am receiving input from all the buttons and joystick. Unfortunately every emulator has a somewhat different control layout on the keyboard and I cant seem to find configuration files for even one of the emulators! Starting with gearboy i tried to edit the .cpp file found some controls but when i get it to makefile it doesn't work. Any tips on changing the control config on the emulators?

Also forgot to say I am mainly looking to use mame4all, genesis, snes and nes I imagine the process for all of them is a little different just spent a few hours messing with gearboy with no success got errors when i tried to make the file with the controls i chose

edit again:

Just read that gearboy has the controls hard coded into src/input.cpp so ill give that a try I havent tried snes/nes yet so will give that a go but if someone has some help on the genesis and mame4all that would be great!

Thanks
