Dolphin / Gamecube / Wiiware / Wii Compatibility on Pi 5

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'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.

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.

Sorry to bump an old post, but I was wondering if you could share how you got RE4 to work on the Pi5? I have Mesa installed, but it’s still washed out in game and I’m not sure what I’m doing wrong.

If I choose Vulcan, the game is slow and washed out. If I choose OpenGL it is the right speed, but washed out.

Thanks in advance.

@Scapps You need to use that dolphin-rpi fork based on 0lder version of dolphin for RE4 on the Pi.

That's one option, however there is an easier way using that newer version of Mesa imo. @Scapps when dolphin starts what does it say in the top left corner in yellow? It should mention mesa25.1 something. Raspberry pi OS has Mesa by default but the newer version of Mesa has the dual source blending support that are needed for a bunch of games that handle textures slightly differently

@retropieuser555

Thanks for the response.

So, I didn't have 25.1 installed, so I got that done and the wash out is going, but now I have a ton of glitching when I move in the game: textures dropping in and out and the like. I am running it on OpenGL. If I switch to Vulkan, the wash out returns.

retropieuser555

@Scapps interesting, is that the case in other dual source games? Such as Double Dash or Battalion Wars? Can you post your settings for gfx.ini and dolphin.ini from the config folders? Also do you have any RE4 game specific ini settings?

Also yeah, the correct in Mesa 25.1, the dev has corrected it for OpenGL's driver, not Vulkan (yet anyway, I think they have a ticket open to work on that)

mesa (25.0.7-2~bpo12+1) is now available for the Bookworm stable-backport
