after much trial and error i slouch here triumphant yet stumped.
i have my analog controllers wired directly to the gpio. Emulation Station sees them but i guess only as SNES controllers. When it trys to map the keys it asks for more inputs than i have buttons. i had to disable SNESDev from the setup menu and configure with gamecon_gpio but that defaults to SNES. i used modprobe gamecon_gpio_rpi map=0,0,2,2 to attempt to override but no luck. i have no es_input.config to speak of. any ideas?
