I build my on arcade with Retropie version 1.10. So I used 6 Buttons (http://www.arcadeshop.de/ILSA-Buttons-Pushbutton-SL-gelb_557.html) and a joystick (http://www.arcadeshop.de/Seimitsu-Joysticks-LS-32-Seimitsu_667.html). I connected them directly to the I/O pins (GPIO) of Raspberry. I used the retrogame software from adafruit (https://learn.adafruit.com/retro-gaming-with-raspberry-pi/buttons) to map the I/Os. This is working and for example Button 1 is know emulated as “Y” on the keyboard.
I tried to config doom and so on with the arcade controls and it works, but then I tried to use the arcade controls for MAME without access.
I tried to configure the controls at the Input Configuration site. This one works and raspberry recordnized my buttons and the joystick. Then I tried on the Input Configuration site to open RGUI. Here I tried to configure also the controls. But when I try to change for example Button A the software didn’t recordnize my arcade controls on I/O port. This problem is only on th RGUI config. All other configs are recordnizing my controls.
Can somenbody help me?
For better understanding. My Retroarch does nor recordnize my keyboard. If I go into the Input config and try to change a button, for example from key “X” to key “B”, the Retroarch does not recordnize my key input. Only the ESC button is working in this config.
