The exact model is "Reyann Zero Delay Arcade USB". But I got it working - turned out that, without the aid of the chunkier Pandora joystick connectors, I'd put the 5 pin joystick connector on the wrong way round!

I just added an exec functionality to my multiplexer:
The idea is, to allow external programs to be executed on a button press. This can be used to enable/disable special functions which are triggered by external executables:

Here is a demo and you get an idea why I need this functionality:

hi bud thanks, if you dont mind asking, how would i go out about downgrading "kodi-peripheral-joystick" i been searching for 2 days now.
if 18.1 has been fixed with updating packages then ill just stick with 18.1 i might of miss this in the fourms thank you alot.

I had similar bug couple of times but each time it was gone after reboot
pi3b+ retropie 4.4.4

@mitu due https://github.com/pimoroni/Picade-Sketch/blob/master/Picade/Picade.ino i think it's pretty time consuming reconfigure the hardware due the picade-hat is recognized as a keyboard. I just changed forcing the value : input_movie_record_toggle into /opt/retropie/configs/all/retroarch.cfg to be not 'o'.

@chmaruni in case anybody else has this problem: I upgraded everything, including upgrading the distro from Jessie to Stretch, then upgraded all the retropie modules, and then (and that was important) I deleted the sdl-vicerc config file. After that, sound and joysticks are working again. Deleting the config without the distro upgrade didn't work for me. Anyhow, seems to be working again.

RetroPie does controls per controller/encoder name, so if two controllers share the same same name, if you change one, you change the other. If you have 2 different controllers using the dragon rise encoder, but they are different, it may be that one is wired up differently than the other.

All solved and work as expected after modifying mupen64plus.cfg from:
# Controller configuration mode: 0=Fully Manual, 1=Auto with named SDL Device, 2=Fully automatic
mode = 2

to:
# Controller configuration mode: 0=Fully Manual, 1=Auto with named SDL Device, 2=Fully automatic
mode = 1

I have done my own mapping, at the end:
0_1531725491626_2d77c9b5-705b-4701-adca-ef13e511e992-image.png

I had the same problem, but with my controls being turned 90° in th setup screens. Seems like those screens don't care about ES' controller configuration, but that can be easily fixed by connecting the joystick's microswitches in the "right" order on the encoder – if you're not using its single Sanwa port, that is.

@mhutter please, paste the content of these files in ghostbin.com (or something similar):

/opt/retropie/configs/all/retroarch-joypads/NAME_OF_YOUR_JOYSTICK.cfg (more than one file). /opt/retropie/configs/all/retroarch.cfg /opt/retropie/configs/nes/retroarch.cfg

@edmaul69 Hello! Well I've got Boulderdash running with vice (not lr). But Im going to re-install Lr-vice again. But heres what works for me. in case anyone has the same difficulty.

[All from the ViceMenu GUI]

1- Restore defaults from 'settings management' (this is a different pref set than the package, you can tell as it changes the display filter to emu crt display)
2 - Set Machine settings / Joystick settings / Joystick device 1 -> Joystick
3 - Set Machine settings / Joystick settings / Joystick 1 mapping -> !Go set this!
4 - Save your settings in 'settings managment'

I think my naviety was !assuming! that because I've configured controllers for retropie that the mapping would naturally carry over to the emulator. Not for vice it seems. Lesson learned.

On the keyboard front, I loaded up the mac version of Vice, found the symbolic and positional keyboards for mac. I then loaded those into the C64 rom section. Then loaded those keyboard layouts in vice. However this made no difference. Unless you have to save the keyboards .kvm's in a specific location I think keyboard mapping is broken in vice

What worked was the virtual keyboard. And knowing that you have to press f1 to start the game. Yep pressing fire button wont do jack (it's 1984) https://ia600707.us.archive.org/20/items/Boulder_Dash_1984_First_Star_Software/Boulder_Dash_1984_First_Star_Software.pdf

Thanks Edmaul for the tips to keep lookin.

@colebeansbroskie if you have two sets of joysticks and buttons you have to set up the buttons the exact same way. You never have to configure player 2. Once you set up one, after rebooting your system both will work. If the buttons are different on player 2, it means you put them in the wrong order. You need to set up player one then reboot. Then go into a game that uses all your buttons and in that game press a button on player one and see what it does. then find that same button on player two. Now put that button in the same spot player one has it. Keep doing that until all the buttons match.

ive noticed it hard to do special moves in street fighter when a diagonal is needed.

Sure thing, I'm not using attract mode for the amiga just thought it may help

@edmaul69 that worked perfect thanks for the help

@mediamogul the flashback ones came in two small ziplock baggies. Then i put my homebrew ones in a small ziplock baggie as well.

The default virtual keyboard (matchbox-keyboard) has an issue where the desktop becomes unresponsive while the keyboard is open, so use xvkbd instead. I'll edit this post with instructions later
