Does anyone here use the GPIO pins for input? I used them on a box controller I made and I am thinking of using them again on my next bartop. On my first one, I used retrogame but I have recently figured out GPIOnext. One of the things I found was to turn off the hot key delay to help lag.
gpionext set combo_delay 0
Does anyone use either? Do you notice a lag at all? I did not really notice any on my box controller.
The thing I like about those options is the fact that I can set the controllers as keyboard and then when you plug in a USB controller, you can use either for player one and two or you can make the plugged in controllers be player 3 and 4 instead for 4 player games. Just wondering if anyone else is going this route.
