@sugarfree Ok nevermind. At first maybe I thought it was an rvz vs ciso thing, but I just loaded the .ciso 1080 Avalanche 5 times and on the 5th time it crashed. So I don't think the file type has anything to do with the random crashes.

These lines appear in the standalone version too but only affect the intro. The game is working without issues.

@sugarfree Ok that's great to know about the Vulkan driver. I do have it installed and working on lr-flycast-dev but was never able to get it running on the standalone version of Dolphin. It keeps throwing me an error.

So I'll give these scriptmodule changes a try right now.

Thank you!

@TPR I think that's this option:-

[Video_Hacks] DisableCopyToVRAM = False

you'll need to check the options they have documented on retroarch's wiki:-

https://docs.libretro.com/library/dolphin/

Although they're not named the same as regular dolphin so you might need to trial and error a bit

@mitu It worked. Thank you!

There was already a bug report - https://bugs.dolphin-emu.org/issues/13416. Furthermore, the Libretro port is not maintained by the Dolphin team, so your report will probably be closed/forwarded to the libretro repository.

@retropieuser555 yeah that's most certainly an option, but from what I've seen on the standalone, it isn't much different from the libretro core where you just go and manually load up the next disc, right? Disc Control > Eject Disk > Load disc.

That seems to work fine, I was just surprise to see the m3u format didn't want to pre-load the disc images.

@retropiedude said in Dolphin or lr-dolphin change emulator on RetroPie to OpenGL or start from:

Oh, that's interesting. Any idea what it's cause then?

Seems that Dolphin uses a Vulkan/GL extension which is not supported by the Pi5 drivers - https://gitlab.freedesktop.org/mesa/mesa/-/issues/10250. The issue has also been reported to upstream Dolphin, but I doubt it's going to be solved, in a reasonable time frame or at all.

Emulator crashes on the Pi5 (which is still pending support) are usually caused by the 16K page kernel used by default in RaspiOS. TL;DR: modify /boot/firmware/config.txt and add kernel=kernel8.img at the end.

If you wish to run the standalone emulator, you can modify the controller bindings by starting the GUI and using its configuratoin menus. Install the desktop, then start it and then execute /opt/retropie/emulators/dolphin/bin/dolphin-emu to get the emulator's GUI/menus.

@AwesomeKingClem I am just now finally getting to it. Sorry about that!

So I finally bought Double Dash because I wanted to try it out on my Pi4 using dolphin-rpi. At first the game speed was really poor (~60% fullspeed). That said, I found this hack that gets Double Dash playing at fullspeed by cutting the framerate from 60fps to 30 and activating the game's internal frameskipping:

I added the following commands to the GM4.ini file in ~/DolphinConfig5.0/GameSettings:

[Core] EnableCheats = True [ActionReplay_Enabled] $Force 30FPS [ActionReplay] $Force 30FPS 0448C388 00000002

(source: https://www.reddit.com/r/gpdxd/comments/flq57f/near_fullspeed_double_dash_with_30fps_code/)

Note that my Pi4 is overclocked 2350MHz/940MHz. The games runs a bit choppy at around 23-28fps but the game speed seems to basically be fullspeed. It's very playable on the Pi4 with this hack.

I am not sure how helpful this hack will be for Pi5 users at is sounds like Double Dash runs at fullspeed regardless and I am not sure if this hack will help with multiplayer. That said, I mainly wanted to share this for any Pi4 users out there. It definitely made a huge difference for me playing this game.

@pgcudahy said in Analog trigger on lr-dolphin:

and the triggers are now bound to an axis and not a button

Right. That's good, that's what they should be.

@satella You can still use vulkan for the other cores using your previous config by editing /opt/retropie/configs/gc/retroarch.cfg / /opt/retropie/configs/wii/retroarch.cfg. Add a line (near the beginning of the file) to set the gl / glcore video driver in the file with:

video_driver = "gl"

so that video driver is used only for the gc and wii systems.

@mozvillat Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Get a verbose log from the error run and post it on pastebin.com.

@norstein
See this thread
https://retropie.org.uk/forum/post/238116
It explains how to launch the GUI for dolphin so you can get in and configure the controller.

Once you get that open you can reference
https://dolphin-emu.org/docs/guides/configuring-controllers/
for a more detailed guide to specifically setting up the controller.

I have to apologise - I got the same error! Was caused by a recent change: https://github.com/mupen64plus/mupen64plus-ui-console/commit/e147b94f3c82866a42e3f72820e73c441158e7d5#comment

it has been reverted following discussion here: https://github.com/mupen64plus/mupen64plus-ui-console/pull/61

Please try again and it should work.

Try changing the video driver in retroarch to vulkan or glcore (working for me). The gl implementation is currently busted but you can try the workaround: https://docs.libretro.com/library/dolphin/

There is also currently a bug with this core and the GL driver that can be worked around by going to settings > user interface > show advanced settings ON and then going to settings > core > allow cores to change the video driver OFF.
The Dolphin core will now work without issues.

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-utils

Test Vulkan (successful example):

vulkan-smoketest

Modify 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.cfg

After 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.
