Just pair the 2nd controller as you did with the 1st one and - if they're identical - that's all. When starting a game, both controllers will be available as P1 and P2, there's nothing else to do.
If they're not identical (i.e. one is a genuine, one is a clone), you'll have to configure the 2nd controller in Emulationstation, just like you configured the first one.

Please test and report on whether the joystick binding patch (as well as dosbox in general) works as expected: https://github.com/RetroPie/RetroPie-Setup/pull/2646

I am not good enough. I was able to follow Dudleydes instructions above and that worked, but I do not know how to get this patch to my retropie. I tried to update "dosbox from source" but that did not work.

The PR already been merged, so update your Retropie-Setup script and then update dosbox to get the patched version.

Have you tried dosbox-sdl2? It might have better joystick handling.

I forgot about this because I updated and I can verify that it works. We are not using dosbox-sdl2 in our keyboard 2 joypad project since its not needed. The keyb2joy.pad project document and index keys assigned to functions. We basically fill in columns with the keys used for things like "jump", "move" or "fire". I have then made an utility that produce authentic DOSBox .map files with full Retropie-support based on these profiles. So far we made 550 platform games fully playable on joypad and we are 20% through the 600 shoot-em ups on the DOS platform.

@dudleydes Thx!

@cousinsfan pretty much. You can buy arcade usb encoders which are basically a controller that you can wire up arcade controlls to. Get 2 of them and wire up each side as a separate controller.

This is my workaround:-

my /opt/retropie/configs/all/autostart.sh:-

python ~/MFRC522-python/rfidlaunch.py &
emulationstation

my rfidlaunch.py contains:
subprocess.call("/home/pi/nesmario.sh &" , shell=True)
when a corresponding RFID card is detected

this nesmario.sh
contains :
/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS nes '/home/pi/RetroPie/roms/nes/Super Mario Bros..zip'
emulationstation

this means my RFID script runs all the time, when the RFID card is detected in emulationstation it kills emulationstation, runs the rom as user pi and when the rom has quit relaunches emulationstation.

Thanks for all your help everybody

the problem was that your foundation was wrong i think.

my theory: during https://retropie.org.uk/docs/First-Installation/#configure-controllers you bound L bottom/R bottom to your L and R buttons. you should have bound L top and R top. this would probably mean that MK would have had sensible default controls (along with SF2, etc), and it would have also meant that you had no SNES button bound to the MAME menu (not that you should need access to it anyway).

@dankcushions

Thanks!
I've understand to use "Controls" for button assign for input.

@dudleydes said in mapping differentcontrollers for C64 emulator VICE:

@niculinux Is your EasySMX controller being detected by your Pi? Can you configure it in ES?

Yes, it is detected, but i have trouble setting the right trigger; once i got in the "configure input" menu and try to set it retropie skips it and reports it as "not assigned". But in the vice menu it is almost impossible to use :,(

@thedatacereal

Not a problem. If you run into any trouble, just let me know.

@coloq said in N64 button mapping woes:

So... ... still having the issue despite what documentation says I should do...

As I mentioned before, if you map the physical “a” button to the virtual “b” button and the physical “b” button to the virtual “y” button it will work as you want.

@thejester Don't enable config save on exit' in RetroArch, it usually messes up your controls. Instead, configure the gamepad in Emulationstation and if you want to fine tune your controls, then use the RGUI to re-map the controller and choose Core Remapping menu to save it per core or game/rom.
Also, when you have a problem unrelated to the topic at hand, don't just hijack it with your questions/problems, just open a new topic instead.

Thanks. I will look in the future.

All,

thanks for replying and apologies for not including some relevant info :-)

So,

Pi 3B
Official Pi PSU
RetroPie Version 4.3.9
Built from Pre made SD image on site
Arcade cabinet with 2x joysticks plugged into generic encoders presented as DragonRise generic USB joystick (no issues with any other emulators/games)
Config: https://pastebin.com/pmUkTEVe
Issue is as stated, load cannonball with no issues, go to config controls cannot set any controls in there, can navigate menu system but left and right perform up and down (if that makes sense)

I have cannonball installed on a picade I made a while back with no issues at all.

any help appreciated

Thanks

Please give more details about your setup as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@douga @mitu I've wired them the same way and it workds, so thanks everyone!

@edmaul69 said in lr-FBA controller config:

@tr3v0r when you set up a 6 button layout it is supposed to be set up as

LXR
YBA

yes there is massive confusion at the moment with 6 and 8 buttons.

the Megadrive/Genesis (6 Button) layout you where using is probably for the megadrive emulator its no good in other cores. Keep in mind to remap your genesis core if your using this as a global

@rsn8887 there is a way to set systems that way. I do it manually in the retroarch.cfg for each system but there is an easier and technically correct way to do it but i dont know how so hopefully someone can tell you.

@jdog35421 said in Controls mess up after I open a game.:

When I restart my pi by turning it off

are you pulling the power cord? if so, you could be corrupting your card!
