Testers Wanted + GPIO Questions

Tue Mar 12, 2013 6:48 pm

I'm no electrician.

I would be very happy if any forum users who stumble into my post and who use their Pi to play retro games could list the emulator used and how well it runs and how many buttons are used in the said emulator.

I would also be happy if any forum users who stumble into my post and who know more about the GPIO pins could tell me how to wire up 17 tact switches to the pins.

Any readers who have put 2 and 2 together, well done, pat on the back etc. ;)

See this post. Read through all of it. Full of useful info. ... 78&t=29962

I am using Pikeyd which uses UInput. UInput simulates the key presses and Pikeyd lets you map the GPIO pins to a key press. I am building a 10 button arcade control running Advmame.

Good luck

AdvMAME works fantastic for me, I've compiled it from source and that took about an hour or so to do. After that I edited the advmame.rc file to change the device_keyboard variable to raw, and installed PiKeyD. I then managed to get a button hooked up to a Pi's GPIO and set as the coin slot.

PCSX-Rearmed works really too, the audio stutters a bit, but the games run fine. Again, you need to compile that which takes a fair while, not difficult, just time consuming.

If you want something that is as simple as a single command to install, DOSBox works flawlessly right through apt-get.

And finally, if you want all of these and NES, SNES, Amiga, GameCube, GameBoy and many others, download the RetroPie script, it automatically compiles and installs all of the emulators I mentioned (except DOSBox, but that's simplistic) and also installs EmulationStation, a neat little menu front end so that you can access all of your games from all of your emulators.

For further reading, I recommend: ... 78&t=29962 ... 00#p307100
