Does anyone know if it is possible to set up button macros for fighting games? I am building my own mini-arcade cabinet and I am using a teensy 3.1 for the USB controller. I have some digital pins still available on it and I was wondering if it is possible to map something like: down, down-right, right+punch button into one button press?
Has anyone tried this or is this even possible through Retropie?
This is out of the scope of retropie – but you could request it as a feature for retroarch – https://github.com/libretro/RetroArch – unless the firmware for your input board can be programmed to do it, which would be another option.
