Raspi & MAME Output System (RGBCommander? GPIO?)
« on: June 25, 2019, 05:18:41 pm »
Hey folks. Got one that's been leaving me scratching my head.

I see people are using various GPIO libraries to run inputs on the Pi, and that seems easy enough.

What I'm wondering is - are there any pieces of software that get the MAME output system to the GPIO? RGBCommander seems to be limited to output devices?

If I'm stuck using a Pacdrive & RGBCommander, does anybody know if it hooks the rank light outputs in Gorf?

I'm going to possibly be building a Pi to Gorf cabinet adapter and would like to do so with a minimum of components. The Nutting/Bally games (Gorf, Robby Roto, Wizard of Wor, etc) are notoriously crap hardware and a small plug-in Pi setup would be a good solution to the problem.

A late reply, but it's possible to pick up on MAME outputs using a PI (and then do something with it over the GPIO pins)... This post shows how I did it with Neo Geo..

I went a bit further and sent the outputs to an arduino to do the credit LED too:

This was all over a year ago.. to be honest, I think we're very close to getting vanilla mame on the PI4, where it should run most things perfectly. Then this sort of thing will likely be very popular. The GPIO pins are perfect for MAME LED outputs.
