Emulation Station Controls

Summary

1. Red A Fire Button is enter or launch game
2. p2 Start White Button is back
3. There is no low lever joystick driver, only simulated SDL Keyboard Codes.
4. The es_input.cfg files seems to use SDL Keyboard Codes to map to keyboard, NOT event test codes
5. 1073741906 0x40000052 SDLK_UP
6. I think the adafruit retrogame driver just converts evtest low level codes to SDL Keyboard Codes.
7. Both front and back register analog #'s in evtest.
