Raspberry Pi 5 - official announcement

TPR

Having an issue with Mario Kart Double Dash using lr-dolphin on the Pi 5. Getting that blue screen overlay during the race that has been reported on the stand alone version of Dolphin and it looks like the fix was to switch from the Vulkan to OpenGL renderer, but that doesn't seem to be an option on the lr-dolphin version. Is there a fix for this or am I just missing something obvious?

@TPR not yet no. It's discussed here https://retropie.org.uk/forum/topic/35172/mkdd-tint-issue-rpi5/10

Perfect. Thank you. I'll keep an eye on that. Not sure why that topic didn't come up when I searched.

@mitu Thanks, i will try to install this package in a few hours and i will report back.

Ok, i install the package and now the emulator is working fine (maybe we must add this package in the script), many thanks!!. But i have issue with the gamepad, it doesn't work, only the keyboard is working. With other emulators i don't have issue.

@abj you need to either use the Dolphin GUI with a mouse and setup your controller or edit /home/pi/.Dolphin-emu/Config/GCPadNew.ini to change the controls for your controller.

Also the Hotkey to exit Dolphin is in Hotkey.ini mine is setup like this:-

General/Exit = evdev/0/8BitDo Pro 2:SELECT & evdev/0/8BitDo Pro 2:START

You can use the GUI to edit that as well.

Not sure I'd be able to get my head around it but I thought there's some auto mapping function now? Maybe I'm mistaken. Or we could do a similar script to mupen64plus where it maps your controller when launching

@retropieuser555 I never saw the GUI, only a board flash for few seconds and the game starts. I will try with the keyboard, thanks for the hint!

retropieuser555

@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.

abj

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.
