[SOLVED] GPIO buttons with NES emulator
  • Billgod
    I setup an arcade with all buttons using GPIO. I have the controls working in PISNES and Stella exactly the way I want. However the advmame emulator for NES does not work at all.. There is no where to configure inputs.(at least I can find) I have tried retroarch and have the joystick working but it won't recognize my mapped buttons. I am using retrogame by adafruit to map my gpio pins to keys. Is there another NES emulator that I can get to work on this thing.. I have found a couple but I need them to have a gui to select the games. There is no keyboard hooked up to this thing. Please let me know if anyone has this working.

    thanks

    Having same problem for advancemame, but works for mame4all and few other emulators.

    I am using Adafruit Retrogame software for my GPIO controls.
  • Billgod
    ok someone HAS to have this working right??

    I figured out this morning. It appear to be that you have to unplug all USB interface attached to PI, I suppose. Then your GPIO control will work on Advancemame.

    It worked for me for menu but haven't tried any games yet but I think it should.

    hmmm I have nothing in the usb ports.. I only have the gpio pins in use.
  • Billgod
    can anyone confirm that they personally have any NES emulator working using GPIO?

    I do. I have been running the adafruit retrogame as well.
  • Billgod
    what emulator are you using?

    Thanks for the file.. I still have nothing when I go into advmess for NES. I have my joystick buttons configured as the up down left right arrow keys. From your file that should work for me. Its like the second admess launches it disables my retrogame??? anyone have any ideas?
  • Billgod
    GOT IT!.. sorry forgot we had a keyboard plugged in.. unplugged and your config works perfect!! thanks
  • mholgatemmholgatem
    haha. Glad you got it! Marking as solved.
