Im trying to get the genesis emulator with retropie v2.3 to have 6 button setup in order to play MKII with all 6 buttons. I have tried enabling in retroarch menu “f1”. when i check on each loadup it is enabled however i dont see where to config the extra buttons to my keyboard i have tried adding keys to config files but i dont think im doing it right. Does anyone have an example of the config files i need or how they get 6 buttons to work. any help would be appreciated this is the last thing i need for my setup.
