basic 2 player support not working correctly

puppetj · 3 Nov 2020, 05:26

i have the raspi 3b+

I had controller 2 one perfect, and controller 2 working also on all games i tried.
So i power down the system and unplug everything, to take over a friends house, well that was a bad idea, ever since i did that i cant get 2 player games to work, there is always a issue with getting them working, and yes i mapped them correctly. how can i get them working again??

Hello and welcome to the forum.

We need more information to assess your problem. Please provide all of the data that's asked for in https://retropie.org.uk/forum/topic/3/read-this-first

Additionally, please be more specific. What exactly means that you can't get those games working?

Finally, you should run the games with verbose logging and show us the contents of the file /dev/shm/runcommand.log.

i can map both controllers fine in , but when i start a game in any system nes, snes,sega, etc.. they get all mixed up and unmapped. (EVERYTHING WAS FINE, when first setting the mapping and playing two player games, as i mention. THEN THIS STUFF HAPPENS:

the mapping when playing 2 player games are mixed up, like half on controller one works and the other half works on controller from controller 1 on controller two, i map i hotkey on controller 1, but it doesnt stay mapped instead it gets remapped to controller 2, the left button get mapped to controller one and the right button will get remapped by it self to controller two,

You didn't mention anything about how you installed RetroPie - which image/document did you use ?

Are you doing the mapping configuration in EmulationStation or from the emulator ? What emulator are you using ?

I used image from retropie.org.uk site for raspi2/3 , i used the docs from https://retropie.org.uk/docs/First-Installation/ and the mapping configuration in EmulationStation. i just run game and it plays, i dont know what emulator its using by default. (how can i find out?)

The name of the emulator is shown at game start, next to the game name (for instance, this is a NES game launched with lr-fceumm):

Is the problem how to get the log from the RetroPie system, or how to show it in the forum?

The /dev/shm/runcommand.log is not accessible via network, you'll need to enable [SSH](https://retropie.org.uk/docs/SSH/] and use a program like WinSCP to transfer it. Since the log is quite large, you can post it on pastebin.com, it's easier to read and find things there.

@puppetj Did you plug the controllers into the same usb ports you set them up in? The USB ports do determine what controller is player 1 and 2. the order is top left is player on, bottom left is player 2, top right is player 3 and bottom right is player 4. If you skip a port, lets say the player one port and you plug a controller into the player 2 port, that now becomes player one. Its a priority system.

even if you map the controllers? i tried many different combos but can you show me a diagram?

lostless · 3 Nov 2020, 21:27

@puppetj yes even if you map the controllers. You are only mapping the buttons, not what's player 1 and 2 ect ect.

setup a seems pretty difficult i dont think i can do that.

@puppetj Don't give up just yet. We can try to walk you through it, one step at a time.

Which of our suggestions did you already try? What worked and what didn't (in what way)?

well the only suggestion i got, related to getting controllers to work for two player, is the usb port order, which never was a issue.

puppetj · 3 Nov 2020, 23:41

@Clyde Im correct that pressing start and select at the same time quit game and goes back to the emulation station menu right? if so why doesnt it work?

I also meant the suggestions for further diagnosis like running the games with verbose logging.

It also depends on the controller mapping. So, if that is broken, start+select may also not work. It also depends on the emulator used, as to my knowledge only the RetroArch / Libretro cores beginning with lr- are auto-mapped by Emulation Station. Other emulators have to be configured manually, see the Docs for that.

Only P1 can use the hotkeys - if you're trying with the P2 controller, that won't work.
Are the controllers working fine standalone (i.e. just one controller connected) ?
