(x86) Libretro Dolphin doesnt load games after update
-
Okay so after building multiple git checkouts. The one working on my x86 setup is the last August commit. All the commits in October are borked or something changed.. Either way, I'll just keep the August commit backed up until I know what's going on.

Curiously, I was playing around with a new installation of 18.04.4 when making additions to an install script, and I experienced exactly the same error on this core. As I was just testing I haven't kept the install - it still works ok on my other machine which runs 18.04.4, but I haven't updated the core packages for a few months possibly (I have updated OS packages and retropie-setup though).
Strange one!

I managed to get the last October commit working now. I switched the video render to vulkan in the Doplhin.cfgs and the dolphin retroarch.cfg
The only game not working is Baten Kaitos: Eternal Wings.
On another note.. There are 3 different dolphin "User / sys" folders. Is that supposed to be like that?

I'm not sure - haven't used Dolphin so far.

I would say not, if using the Libretro Dolphin emulator it's advised to get the latest 'sys' folder from the Dolphin GitHub and copy the 'sys' folder to: /home/pi/RetroPie/BIOS/dolphin-emu/
Can't say i've noticed any other sys folders appearing elsewhere?
If using Dolphin standalone installed by RetroPie, there is only one 'sys' folder under /opt/retropie/emulators/dolphin/share/dolphin-emu

@HoJo215 I'm having the same problem as you, but it's a little unclear how I should go about this reversion. Retropie's build scripts appear to checkout the latest master commit, so it's unclear to me that reverting the retropie-setup repo to an older commit will resolve this problem for me.
Or am I interpreting this wrong? Can I just go into detached HEAD on a specific commit and reinstall dolphin?
If possible would provide a little more direction and a commit hash that would get me to where I need to go?
Thanks.

@mitu perhaps you could lend a hand here?
Can I downgrade just the core, or do I have to revert the entire of retropie-setup repo and reinstall?
As I mentioned before, I'm not confident that this will fix anything because RetroPie appears to always grab the tip of
masterand build from source, so even the old retropie-setup will still build the broken core.Maybe this is the problem?

As I said, I have no experience with Dolphin.

@mitu My question is about how to downgrade a core that's been installed by Retropie-Setup.
It looks like I have to modify the installation script to point to a specific commit. I think. I just didn't want to spend hours walking the bash scripts when two people have clearly already done something very similar in this thread above, but haven't really given enough details for me to figure out what to do.

I got this resolved on my system (Ubuntu 18.04, Intel i5-3470 iGPU) by installing and using Vulkan rendering. I did not have to download the Sys folder from the Dolphin source repo.
I must note that Vulkan is not supported on any CPU earlier than Ivy Bridge, so this may not be a viable solution for some people. Mine is the earliest possible generation chip this even works on, so I guess I got lucky.
Install Vulkan support and testing application
sudo apt install -y mesa-vulkan-drivers vulkan-utilsTest Vulkan (successful example):
vulkan-smoketestModify the GC and Wii cores' config files to use Vulkan renderer:
sed -i '$ i\video_driver = "vulkan"' /opt/retropie/configs/wii/retroarch.cfg sed -i '$ i\video_driver = "vulkan"' /opt/retropie/configs/gc/retroarch.cfgAfter doing this, GC games worked fine. I'll come back and modify this post if necessary whenever I get around to adding Wii to my system.
