Hotkey is set during initial controller configuration. You should be able to have a different one for every (type of) controller you use. Configure additional controllers through the EmulationStation start menu.

Edit: oh but I guess you want to do this only for NES, so the shoulder button still works when using the SNES controller for SNES games... maybe not so simple then. The docs do say that hardcoded configurations are "locked to a specific core and controller," but in the example they give, I don't see anything that does tie it to a specific controller.

@2stupid2dothis When Port 1 and Port 2 device types are set to "Auto" in Quick Menu -> Controls (RetroArch menu), the emulator puts a regular NES controller in port 1 and an Arkanoid controller in port 2. You can use a mouse as the Arkanoid controller in this configuration.

If you want to use a controller's D-pad instead, you can set Port 1 and Port 2 device types to "Gamepad."

@punx45 , I'm about to go almost the same way myself, wiring up buttons from my genuine arcade machine. I'm planning to use the grounding instead of the plus feed (Raspberry's GPIO's should trigger fine on three state i.e. either open circuit going high to feed voltage OR going low to GND).

However, my thought was also a prevention from involentary multi triggering but not by H/W support, we do have plenty of computer power at hand; have a look at this article Physical computing with Raspberry Pi. Some simple sleep timers should do it.

I am so glad to hear that :-)

According to the game manual you'll have to press both buttons for a long jump:

FOR A SHORT JUMP - Use the ARROWS to indicate your direction and press BUTTON 1
FOR A LONG JUMP - Use the ARROWS to indicate your direction and press BUTTON 1 and BUTTON 2 simultaneously.

I should probably just tell you that i did order and received the 2x Tomee NES to USB adapter. They work flawlessly with my two original NES-004E controllers. I have been using them for the past 2 weeks playing top NES games. :-)

I am still waiting for the PSX to USB adapter to arrive. At the moment i have no way of testing my PSX Analog controller.

Thanks for the replies gents- I'm in the UK so it would be to far to post. I will have a think... on which way to go. One thing I didn't check are the new classic nes and mega drive variants the same and on Usb?

How do I remove the udev rule? I don't know if I have it or not. I presume I do because earlier I was attempting to change it.

You just delete the line you added from the file you edited.

@bytethis said in NES Zero:

@yahmez Interesting build. What are you running for emulators ? Just out of curiosity, do you find it's easy to see such a small screen playing , and how long does the battery last ? Nice of you to provide the schematics.

For emulators, anything with the old school standard button layout of of d-pad, a, b, start, and select. The screen is tiny but Gameboy and Gameboy color are perfect. NES is pretty good although text is pretty much unreadable unless you're very familiar with the game. I've been using only NES games which I'm familiar with. The battery lasts about an hour and with the power boost I can charge and play at the same time.

@haemogoblin Yes, it works exactly like that by default for libretro emulators Select and Start exits to the menu. To begin, you should read this https://retropie.org.uk/forum/topic/3/read-this-first and provide info on your setup quickly followed by https://github.com/retropie/retropie-setup/wiki/First-Installation#configure-controllers which explains everything you are asking.

Doh! I did read the documentation but overlooked this. I checked it again after your answer and you're right, it's definitively there. Sorry, my bad.

@ortsac so I tried switching with switched off console, same result. Checked the connection three times now. Should be working but it is not.

Maybe the controllers are not working properly. I cleaned them 1 month ago and I noticed that the rubber pads are not the best. There are stripes on the connection pad. I tried to take a picture of that.

I also measured the resistance of these, and it is >60 Ohms. Should be way lower than that right?

@edmaul69 said in Nintendo Controllers Not Working in game.:

@justintoxicated if you had just deleted the cobfigs you created for 5 controllers in your /all/retroarch.cfg you would have been ok.

I don't think so because reverting the config file through a re-install did not fix the issue.

@briandamico I don't know what caused, but I know what fixed: the changes we talked about here: https://retropie.org.uk/forum/topic/10321/looking-for-testers-custom-joystick-mappings-for-runcommand-retropie_setup-menus/

@meleu thanks that is going to be extremely useful! i think between the two of you i should be able to come up with a solution now. thanks!!

As described at https://github.com/petrockblog/SNESDev-RPi#button-polling a shutdown command is issued when the button on the GPIO adapter is pressed five times. Maybe that signal is somehow inserted into the RPi when you connect your controller(s).
The dmesgcommand might give you some more insights into what the shutdown is causing.

@onsmike Yes, it seems a keyboard is needed. That's what "solved" the problem for me when I tried it last night at any rate. It's a bit annoying, but it works on the roms I tried.

So i've finally got further with this issue. I've removed retropie from my SD card and reinstalled it. Added the correct driver and set every GPIO pin in de conf file to 2 so my config now looks like this: gamecon_gpio_rpi map=0,0,2,2,2,2
Interesting enough now all of my controllers seem to work without the 5v mod or extra wires whatsoever. I've attached the NES pad to the PAD 4 pin. The only thing not working right now is in-game. The NES controller works in the menus of retropie and emulation station but not in an actual NES game. Going to figure that out next!

@briandamico i dont know the name of your controller but its config file will be located in /opt/retropie/configs/all/retroarch/autoconfig/ .
