@abj to get just the GUI for editing without a rom, add this line into the emulators.cfg and choose it when launching runcommand

dolphin-editor = "XINIT-WMC:/opt/retropie/emulators/dolphin/bin/dolphin-emu"

abj

@retropieuser555 You solved the mystery !! Now i have access to the gui and i can change all the parameters! Thank you very much.

@zaphod24

Any additional thoughts here? With only 1 controller attached it is recognized about 50% of the time I boot up. The second controller was recognized maybe one boot out of 200+

@zaphod24 You'll have to reproduce the problem on the bookworm desktop and ask the devs on the raspberry pi forum. I haven't tested, though I don't think it's a RetroPie problem.

zaphod24

@Darksavior I'm unsure why the desktop version would make any difference compared to the lite version. I made a post in the troubleshooting pi forum but there doesn't seem to be much interest in it

https://forums.raspberrypi.com/viewtopic.php?p=2195483#p2195483

Unsurprisingly, the same issue exists with Android 14 on the rpi5 as well.

Darksavior

@zaphod24 It won't, but the only time that I needed help from pi devs, they refused to reproduce it on the RetroPie image.

zaphod24

@Darksavior I used the raspbian lite image and then manually installed RetroPie. Sadly there haven't been any other replies so I would advise anyone that wants to replace their pi4 with a pi5 to get better performance with N64 emulation etc. hold off if they play any games locally 2 player.

@zaphod24 Hey, if you wanted to play 2 player games using your Pi 5 and USB isn't working, why not just use Bluetooth gamepads?

zaphod24

@PiBoyyy Certainly can, but I already have 2 8bitdo USB gamepads which worked fine on pi4

retropieuser555

@zaphod24 certainly seems strange. Not sure I have any USB controllers although I might try and plug in my 8bitdo Bluetooth gamepads via USB to test and see if it gives me the errors that way

zaphod24

@retropieuser555 I'd appreciate knowing how that goes.. I even went as far as ordering a usb hub to try and put both gamepads on the same USB controller for the pi5 since they changed things from the pi4 and have 4 buses, one for each usb connector on the back instead of one usb2 and one usb3 for the pi4.

mitu

@zaphod24 where did you read about the USB buses being 1 per port ?
The RP1 chip, which drives almost all I/O on the Pi5, has 2 USB buses - see https://hackaday.com/wp-content/uploads/2023/10/rp1-block-diagram.jpg or https://www.raspberrypi.com/documentation/microcontrollers/rp1.html#content.

Because im using Pi as a desktop right now. i test my controllers (Logitech 710 & 310) with this page https://hardwaretester.com/gamepad and both are working at the same time. Maybe the issue affect two same controllers or same brand ?

@abj I have played Saturn Bomberman 8-players on the Pi5 in both wired and hybrid (4 wired and 4 wireless PS3 pads - original and Shanwan) and all has gone well, so while it's a good hypothesis, I'm not sure about that angle.

lsusb on pi5:

Conclusion, 4 buses on pi4, 2 usb2 and 2 usb3 and 2 buses on pi4, one usb2 and one usb3. It's possible lsusb is reporting incorrectly or I am misinterpreting the results.

Niether - there are 2 physical connections for each pair of USB2/3 ports. But regardless, I don't think that's a problem per-se and it's not the cause of your issue. Maybe your unit has a problem ? Do any other USB peripherals exhibit the same issue (i.e. keyboard/mice) or it's just the gamepads ?

zaphod24

@mitu so far keyboard and mice have been fine, it's just when using 2 gamepads at the same time

zaphod24

I gave up and got 2 bluetooth SN30 pro controllers. They work without issue except both light just the first LED which makes it look like both are player one when in fact one is player 2.

i sumarized the instructions for the Dolphin standalone emulator.

Update RetroPie-Setup script.
Install Dolphin emulator from experimental packages.
Add to this file:
/opt/retropie/configs/gc/emulators.cfg

this line:
dolphin-editor = "XINIT-WMC:/opt/retropie/emulators/dolphin/bin/dolphin-emu"

In the end, the file it will be like this:

dolphin = "XINIT-WM:/opt/retropie/emulators/dolphin/bin/dolphin-emu-nogui -e %ROM%"
dolphin-gui = "XINIT-WM:/opt/retropie/emulators/dolphin/bin/dolphin-emu -b -e %ROM%"
dolphin-editor = "XINIT-WMC:/opt/retropie/emulators/dolphin/bin/dolphin-emu"
default = "dolphin-gui"

Start a game and choose from runcommand menu the dolphin-editor. This will open Dolphin menu, where we can change the parameters of the emulator and configure the controller(important).

Installed from terminal, a recommended package:
gldriver-test.

This should be handled automatically now - as part of the 'xorg' installation.
