I'm using raspberry pie to run the program, how do I get player 3 & 4 button working? or attached to an ipac2?
The I-Pac is a hybrid encoder that you can easily assign each input port to output whichever keystroke, gamepad button, or mouse click you want.
For an Upright cab setup, you'll need these 10-12 input ports:
- 6 player buttons (L. Run, Jump/Throw, and R. Run per player position)
- 4 Start buttons (1 each for players 1-4)
- 1 or 2 Coin buttons? (optional)
-- T&F
appears to work OK on Free Play. (some games don't)
-- If you want to use Free Play, play-test it
BEFORE you start making sawdust.
For P1, the run buttons are Button 1 (L. Ctrl) and Button 3 (Space) and the jump/throw is Button 2. (L. Alt)
In the MAME dipswitch menu, you can set Cabinet to "Upright" (default setting) and Coin A to "Free Play".
Disclaimer: The older versions of MAME used on the RasPi may have different menu options.
