I cut the traces to the DPAD-Right Button and the Y Button. (On the PiGRRL 2.0 Custom Gamepad PCB)
Then i wired those buttons to GPIO2 and GPIO3 which were unused and changed the retrogame.cfg.
Now i have GPIO 18,19 and 21 free for the DAC.
If one tries to use the MAX98357a with retrogame for a pigrrl-project, the sound will not work if the retrogame-utility is started.
This is in part expected, especially since the shoulder-button for the pg2 uses the pin 12 wich is the left shoulder button, but i would like to reassign this button.
I have tried disabling pin 12 (and to be save 19) in the config, but that does not "free" the pins and audio still does not work.
How do i use this dac with retrogame?
