Sorry i don't understand what this means.

@abj It's nothing important. Just a joke because @retropieuser555 deleted his post, and he was responding to one of mine.

Edit: OOH I tagged the wrong person. My bad.

This is it. You have to start the game from The Gui for the above to work. The game will change automatically the disk and with the press of start bottom will continue to next disk.

I think if you create an .m3u file and toggle the aforementioned option, starting the game from the playlist file should work without invoving the GUI. But I don't think .m3u is enabled by default in EmulationStation for the Wii/GC systems.

I managed to test this and it's working! Disk changed successfully without to launch the game from the Gui. I had to do the following:

-First added to the Gui the path for gamecube roms.
-Set Dolphin option: Automatically change disks.
-Add .m3u support for Doplhin in the es_systems.cfg

@abj you don't need to use a hotkey to change the disk then using that?

@retropieuser555
Disk changed automatically without to press any button or open the Gui.

I tested with Resident Evil 1. Because i didn't find a save file to try the disk swap, i rename the Disk 1 to be the Disk 2 and to 2 to be 1 in the m3u file.

When i start the game (Disk2) from ES (m3u shortcut), in one point, game ask for Disk 1.Then a message appear that disk changing automatically and finally the game start from Disk1.

@mitu is there a way in the dolphin.sh to set the path but it gives the user's name rather than say pi?

[General]
ISOPath0 = /home/pi/RetroPie/roms/gc
[Core]
AutoDiscChange = True

Then we could have this setup by default for users when installing dolphin?

Look at the existing scriptmodule, a .ini file is already created on the 1st installation. You can use either $user or $home to refer to the installation user or the user's home path (not to be confused with $USER or $HOME).

Another one parameter we can add to dolphin.ini 'file, is to hide the yellow letters that appearing in the upper left corner when a game starts.

[Interface]
OnScreenDisplayMessages = False

@abj I find those useful to be honest, I keep it set so I know my game has saved and I can switch it off safely. Or if the wiimote has connected properly etc. The bigger solution would be some kind of answer we had for the mupen64plus.sh script that looks at your controller and maps it if it doesn't exist in the config yet. Especially for things like hotkey. It could be possible seeing as dolphin now follows SDL's standardised Button East, West etc.

Anyway getting ahead of myself there, not sure how much interest in GameCube on pi 5 there is aside from a handful of us on here

I have something in the works here, but not yet complete since I want to see if the settings can be mapped to a profile to be loaded automatically, especially since Dolphin doesn't have the concept of 'auto-configuration'.

I guess you could at command line level change the PadProfile1 when booting depending on the controllers.

But then the hotkey is inside it's own .ini, so not sure how you'd get around that

Yes, that's part of the solution, the other part is the hotley mapping and determining which profiles to load (for multiple controllers).

How have you been getting multi-disc games to work?

I've tried using an m3u file but lr-dolphin doesn't seem to load it.

for example. .m3u file contains:

/home/pi/RetroPie/roms/gc/B/Baten1.rvz
/home/pi/RetroPie/roms/gc/B/Baten2.rvz

but then it just kicks me back to ES with the following error in my log:

[libretro INFO] 38:09:360 DolphinLibretro/Boot.cpp:177 N[Video]: Using GFX backend: Vulkan
[libretro ERROR] 38:09:360 DolphinLibretro/Boot.cpp:193 E[BOOT]: Could not boot /home/pi/RetroPie/roms/gc/B/Baten.m3u. M3U contains no paths
[ERROR] [Content]: Failed to load content

Any ideas?

I haven't tried this emulator yet, but I believe that all libretro emulators work the same.

So, try the .m3u file structure like this:

game_disk1.rvz
game_disk2.rvz

Or like this:

game (Disk 1).rvz
game (Disk 2).rvz

I did... same error. :(

EDIT: I should mention that all my other .m3u files are working just fine on all my other consoles: Saturn, Dreamcast, X68000, etc, etc... so this is not my first rodeo with the format.

So someone over on reddit pointed this out and have been testing a little bit. For certain games playing with the under clock function seems to help smooth some of the games out that were on the edge of playability. So things like skies of Arcadia have a few slowdowns but putting the under clock to 70% seems to have smoothed that out. It might be worth playing with those settings for some games to see what it fixes. Although for a few it makes no real difference (Luigi's Mansion for example)

@retropieuser555
Thanks for the tip. Is this for the standalone version or Libretro, or both?
