Dolphin / Gamecube / Wiiware / Wii Compatibility on Pi 5

@retropieuser555 how does one run Dolphin standalone? I've only figured out to run it through EmulationStation

How did you get Mario Kart Wii to work? Whenever I load it up it says that it could not read or write to Wii system memory, asks me to make a new file, and says that the save data is corrupted.

@AWiiEnthusiast not sure, I suspect similar to your Mario Party 5 problem there's some issue with your config files or your roms in some way.

Unrelated but I'm gonna leave this here. The most recent update on Dolphin gives access to Retroachievements when using allowed cheat codes, such as 16:9 wide-screen & 60fps modes

Apologies bumping my own thread but I noticed in the Mesa 25.1 release notes the fix for dual source blending has been implemented in v3d driver

https://docs.mesa3d.org/relnotes/25.1.0.html

I'll give this a go in a few days when I have some time, but chances are this will fix a few specific graphical errors that happen on GameCube, psp etc like the mario kart double dash blue screen

Edit: Okay I build mesa 25.1.0 direct from gitlab, have to install a bucket ton of dependancies for building and use OpenGL rather than Vulkan as the video backend, but Mario Kart DD and Resident Evil 4 both work perfectly now. Even one of my favourite Wii games: Zack & Wiki, is working perfectly compared to the graphical mess it has before.

I've done and further testing and it appears this is the best way to play gamecube/Wii now, it does more than just fixes the graphical glitches in the handful of games.

Using mesa 25.1.0, various problem games such as Star Fox Adventures, Mario Sunshine, Luigi Mansion, the frame rate is now better than Vulkan, which in itself was a boost compared to original open GL with the stock mesa version that comes as standard with the pi 5.

I'll go through and test some other games that are in the yellow or orange on the spreadsheet. But I do feel that Mesa 25.1.0 with Open GL is the best default option to use (of course some games still require other tweaks, such as fast disc access for Simpsons Hit & Run; even my fast MacBook needs that)

If you install mesa and get an error and emulationstation won't load, make sure you've installed vc4 as well as v3d.

No change on my side (I used the backports)

retropieuser555

@DTEAM I'll take a look, debian bookworm backports is 25.0.4 right? The commit I'm looking at is on 25.1, so might need to wait a few days for backports to be updated

https://packages.debian.org/source/bookworm-backports/mesa

Edit : actually it seems backports is around a month or so behind based on when 25.0.4 was released in April

Also 25.0.4-1 for me

I'll wait for the Bookworm-Backports update. I saw a similar bug (white screen) on aethersx2 (PS2) with God of War II (Pegasus race just before Temple of Lahkesis). I'll check if that update will change something.

It might not do much for aethersx2 as Open GL doesn't work for that for some reason, only Vulkan. Maybe if a dev comes along and works on arm64/aarch64 support for PCSX2 someday

@DTEAM I was just curious, what command(s) are you using to install your new MESA drivers via backports on your Pi? I tried manually compiling 25.1 on my Pi4 but I am getting a compiler error and I think it would just be easier to go with the backport route for when these new drivers become available.

I am really excited to hear about the performance improvements with the 25.1 drivers. I would really like to try this out on the Pi4 and see just how much of a boost it can provide for Gamecube/3DS emulation.

@gvx64

Follow the instruction on my last post here

If you use sudo apt install -t bookworm-backports mesa-va-drivers MESA will not be broken. With this, you don't have to play with dependancies.

Edit: For now, Bookworm Backports = mesa (25.0.4-1~bpo12+1) and not 25.1.
