Do I need two coin buttons?
  • piplayah
    I am focusing on mame games.
    I am making two joypads with old arcade controls.
    I am using the https://github.com/ian57/Raspicade-Retrogame-2Player-BPlus

    player 1 joybad has a button linked as the "player 1 start".
    player 2 joypad has a button linked as the "player 2 start".
    You only need a single button for putting in coins right?

    The reason I'm confused is this... the retrogame.c file also has a credits / coin button for player 2, but is this needed?

    From the github page:
    GPIO 13 -> KEY_5 // Button Coins/Credits P1
    GPIO 26 -> KEY_6 // Button Coins/Credits P2

    Can I manage with a single coin button?

    You can manage with a single coin button. You just map p1 coin and p2 coin to the same button. So when one person hits the button, both players will receive credits.

    Thanks! I think I can figure it out.
