I show off my modded Arcade 1 Up Simpsons control panel that is running off the stock Android OS soft-modded with Mame4Droid and RetroArch with Final Burn Neo (core).
Each player position is connected to an individual encoder board.
Buttons are swapped with IL Happ and EG Starts.
Joysticks are original but the connections had to be desoldered so I could use quick disconnects.
The Trackball is stock and connects to the Thunder Stick 12-in-1 interface board which then connects back to the Simpsons encoder board.
The Power, Volume, and Headphone jacks are unchanged.
I also show how the online Simpsons and Simpsons bowling still work, but you need to have a unique set of controls connected to the original encoder board in order to play the games.
Hope this video inspires you to try something new!
