Yes I know it. But how to connect it together when you will insert coin it will let you only one game.kusti8 wrote:Adafruit has a single coin acceptor and a four coin acceptor. I believe that wires to one of the GPIO pins which you can detect in python. Don't have it so not sure how it works.
You'll have to do that with programming in the game (or in a script wrapped round the game). For each coin accepted you'll add 1 credit, multiple credits or a fraction of a credit, for each game played deduct 1 credit, keep the balance in memory.tomassk wrote:Yes I know it.

Thank you and what emulator should I use ?DougieLawson wrote:You'll have to do that with programming in the game (or in a script wrapped round the game).

A multiple coin acceptor can do some of that stuff for you. https://www.youtube.com/watch?v=G_ubo3hjXhI
Thank you. Can I use RetroGame from Adafruit GPIO to USB utility ?Jessie wrote:For Space Invaders any version of Mame built for the Pi will work. The facilities for adding coins are already there. You just need to pull wires from the switch on the coin validator to whatever interface device you will be using for input. For arcade cabs I use minimusAVR with KADE firmware loaded. The pi will just see it as a keyboard or joystick depending on which options you select.
