Like I said in my previous post I had to rotate my joystick for 90 degrees so I needed to figure out how to change the controls to fit my new layout.
One thing that annoyed me with AdvMAME was when you map exit from the emulator to Select + Start you get this nagging message asking to “Continue” or “Exit”.
In order to remove this message find in /opt/retropie/configs/mame-advmame/advmame-1.4.rc following line:
and change to
Following configuration I have edited through AdvMAME menu to fit my rotated joystick setup, and it can be found at the end of the same file:
input_map[start1] joystick_button[0,7] or keyboard[0,1] input_map[coin1] keyboard[0,5] or joystick_button[0,6] input_map[ui_up] keyboard[0,up] or joystick_digital[0,0,0,0] input_map[ui_down] keyboard[0,down] or joystick_digital[0,0,0,1] input_map[ui_left] keyboard[0,left] or joystick_digital[0,0,1,1] input_map[ui_right] keyboard[0,right] or joystick_digital[0,0,1,0] input_map[ui_cancel] joystick_button[0,6] joystick_button[0,7] or keyboard[0,esc]
Just in case you find yourself in a situation where you mapped your menu key wrongly or you have made some other mistake, it is safe to delete these lines and start over mapping through AdvMAME menu that you can enter with TAB key by default.
