Dolphin emulator running on RP4B 64bit

George Spiggott

@wodak Thanks I will try that in a few days. I got my hands on the new 64 bit Lakka so I'm using my SD card and experimenting with that at the moment. I will of course report back here somewhere if there is any useful info for PS1/PSP/DC/N64 etc.

I've added some more games ...

Micro Machines (runs OK)
Super Smash Bros. Melee (lag)
Mario Party 7 (lag)
Super Mario Strikers (lag)

@wodak Nice that you are doing some more tests.
To be honest i am kinda giving up hope on making dolphin being usable on the pi4. My last hope was vulkan mature enough to make it run but your tests seems to go the other way around.

Another test you can make since you are not using vulkan is to not launch dolphin through a x11 session like you are doing and maybe try running via gbm, in my tests with ppsspp on opengl i had better performance just by not launching the desktop and since dolphin has command line launching options, maybe it improves enough to make it useable.
Another thing is to make dolphin create shader caches before launch. In your videos ive seen some stutters that maybe are because of that, but i cant remember if this is a vulkan feature only.

Cool, brother, thanks for your tests.

@pi4papiba

Yup...was thinking the same as you. I came to conclusion that PI4 is just not powerful enough to run Dolphin on decent level. We'll have to wait for next generation of Pi5 to arrive :)

tnx for the tips but I think I'm done with testing....might be a bit better when Igalia finishes optimizing Vulkan driver....

The stutters and tearing is mostly appearing in games if you play them full screen. In windowed mode they work kind of better (less tearing)....

@wodak Seems like when 64bit is out of beta GameCube will be for raspberry pi 4 what N64 is for raspberry pi3. Some games run fine and others don’t.

@wodak Hi!

your guide is a gem. It helped me run dolphin on my raspberry pi 4. There is one thing that I want toaccomplish and I couldn't find any relevant help on the internet.

I want to link the dolphin executable with the mesa vulkan driver but not system wide. In other words. I have compiled and installed Vulkan using a custom installation prefix under /opt directory in order to not break something in raspberry os which comes with official mesa installed. How can I direct dolphin to the custom Vulkan drivers under /opt directory in order to use these instead of the system's default during compiling ?

Thanks in advance for your help

Kind Regards

@wodak What does the “full-upgrade “ command do? I use “upgrade”. Is that better?

Full-upgrade is used in preference to a simple upgrade, as it also picks up any dependency changes that may have been made.
Check the documentatuon.

Sorry..... but I can´t help you here...maybe ask on dolphin forum...

@wodak thanks for clarifying

This may be of interest. Currently it only runs on Android as far as I know.

There's a video about it here. Worth noting that by 'mid range' he means A76 CPUs (Mediatek Helio G95 and Snapdragon 730) .

@george-spiggott

I was wondering too if anyone here had tried building this for the Pi4.
It sounds like there's been a spat with the Original Dolphin team or something. As the creator said he'd stopped work on this version, started another, https://github.com/Bankaimaster999/Dolphin-MMJR2 which apparently he also put down?
Allegedly?

I've been playing a bit with emulation with Dolphin again. So I've updated the Mesa drivers to version 22.0.0 dev and ran Dolphin again. The results are a bit better. It runs a bit smoother (maybe 1 or 2 frames) and less glitches in games. But still not really playable.

Just for the info. I tried 5 different dolphin emulators on Lineage 18.1 (64 bit).
Dolphin , Dolphin Ishiiruka , Dolphin MMJ, Dolphin MMJR and Dolphin MMJR2. It runs even worse than on Rasperry Pi OS 64 bit...

@wodak I'm trying to do that too using the new Raspbian Bullseye 64bit.
For some reason when following the steps here I had to keep manually installing different packages which didn't install from the dependencies listed on this guide, and had to look up the proper names for most of them, but eventually it let me build Mesa version 22.
I am suprised tho that you didn't get better performance, I'll test and see how it goes.
But I have already tested on a regular Pi 4, 4GB running Konstakang Android 11 and was able to get better performance running the MMJR build of Dolphin. I'd say it was close to full speed for some games, but still gotta do more testing of easier to emulate stuff and report back.

Trispc

So I've tried doing this guide and managed to install the latest Vulkan drivers in Raspi OS Bullseye, however I can't get Dolphin to install. I'm following the steps exactly.
Am I missing anything?

I'm still on buster...I'll wait till Raspberry Pi OS becomes stable on bullseye and then I'll try again...but I don't except any kind of miracles :)

I still think that RP4 is not really capable of running Dolphin at decent level....

I didn't update my Dolphin to the latest version.....maybe you shoud try a more recent installation of Dolphin described in Building Dolphin on the Pi 4: 2021 Edition from bomblord.

Any updates regardin dolphin on rpi4?

@pscotto1234 I managed to build the libretro version and sin and punishment 2 ran at like 10 fps. It was just a test. I have an arm-based mac mini for that.

Pi4 at 2Ghz. Bullseye 64bit lite. Latest stable kernel. The last mesa driver I could install was 21.3.x I think. 22 wouldn't build. I managed to build retroarch with vulkan but I couldn't get any emulator to work with it. It wouldn't have helped anyways. I only saw an improvement for flycast when I tried it on batocera which has vulkan pre installed.
