@lurker Thnx. I checked out the USB encoder product and seems like this is the correct product for easily adding autofire. Maybe it would be possible to do it with the controlblock as well but requires more skills than I have. I like the power switch feature and ability to connect two cotrollers to the controlblock but the dufficulty of adding cooling solutions with how it stacks on top of the pi is annoying.

@backstander Thank you so much! Am digesting your answers and will get back to your with questions/pics for anything I don't understand.

@mitu notepad ++... cfg file. Might just try to revert retroarch, seems challenging for the non tech saavy tho. Or just remap over about 80 remap files
