Dolphin emulator running on RP4B 64bit

@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. -

@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
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) .

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

Am I missing anything?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.

So, not much better than it used to be in opengl.
I really thought vulkan would make some of my favorite games playable.Have you tried Wind Waker? in my tests with opengl it run almost playable a year ago, around 20-25 fps in the initial village. At the time, vulkan was super glitchy but there was improvements already.
I really want to give it a try since the last time i did it was like 6 months ago but it would be super time consuming and i dont have the time right now to build everything from scratch.
Another thing: using vulkan you can tick an option in dolphin settings to do HW texture decoding. It should improve performance.Edit:
heres gecko code to try running double dash in 30fps mode too[ActionReplay_Enabled]
$Force 30FPS
[ActionReplay]
$Force 30FPS
0448C388 00000002Anyone really smart here who follows the Raspberry Pi Scene much?
The Pi4, they're working on some kind of better GPU driver, have been since launch. I'm wondering if once that driver ships that it'll speed things up?I'd love to see 24 / 30fps solid Wind Waker on the Pi4.
I don't think we'll see a Pi5 for at least 3 or 4 more years to be honest.

@GoshGeeGolly The latest bullseye pi os update does not include vulkan. At this point you might as well wait for a pi5 and the next version of the pi os.
I recently figured out how to properly install vulkan by using pikiss instead. Even then, you need retroarch and the cores compiled for vulkan. Retropie does not do that. Pikiss includes pre-compiled binaries but most of them crash when switching to vulkan. Only lr-flycast worked for me and I did notice a speed increase.
It's been a few months since the last time I posted here and I haven't changed my opinion. Get an old pc instead.

@Darksavior does flycast run slowly on that many games though on an overclocked 32bit pi4? I've only ever found Shenmau runs at a little slower than the games on a Dreamcast (that I can notice from the original games I own anyway)
Definitely agree about waiting a few more years for Dolphin on a pi though. It'll be when the next revisions have that bit more grunt power to handle it.

@retropieuser555 I usually test sonic adventure 2 since the slowdowns are seen right at the first level. CPU 2000/GPU 750. There are a lot of framedrops on that downhill. With vulkan those are almost eliminated.
Without vulkan, the standalone version of flycast is faster than the included retroarch version. Cmitu has a wip script if you want to try it. Loading games from ES loads to flycast's menu instead. https://github.com/cmitu/RetroPie-Setup/tree/flycast-standalone
I'm not sure what's up with redream. Overall, it's way faster than any version of flycast but the huge frame drops to the point where it can make the game freeze for a split second makes me go back to flycast.
