Dolphin / Gamecube / Wiiware / Wii Compatibility on Pi 5

@retropieuser555 I don't know if it's like psx that you have to enter the disk while the emulator is running or it is like dreamcast. SO far i just boot from disk two of Resident Evil to test how the disk swap is working.

Yes, I hope it will be possible to control Gui with gamepad.

I asked on discord, in some games emulator must be running to change the discs.

I managed to change the disks from the Gui without issues. It's the best approach so far. The only thing that missing to make the experience near perfect (for a standalone emulator) is the control of the Gui with the gamepad.

First set as game folder in the Dolphin Gui the gc folder in the roms folder of RetroPie.
Configure correctly the gamepad from:
Dolphin GUi -> Controllers: evdev device/ gamepad. After configuration i create a profile and save.
Create some neceserry shortcuts from:
Dolphin Gui -> Options => Hotkey settings. I create one shortcut for open and exit .
Set automatically disk swapping from:
Dolphin Gui -> Options -> Configurations -> Change Disk automatically.

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.

Now i have to find a way to create a launch script to open the Gui, similar to scummvm and amiberry.

Maybe is possible to control the Gui with the gamepad with the use of xdoxdrv: https://retropie.org.uk/docs/Universal-Controller-Calibration-&-Mapping-Using-xboxdrv/

@abj if you can use a mouse or keyboard on the gui, then yes you can use xboxdrv to map it for that.

might get a conflict when you play a game though since you have the controls mapped elseware.

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.

It's worth noting Dolphin itself has a "automatically change disks" option in the config/GUI. No idea how that works though or how it would know when to swap, bit of googling suggests you can use an m3u for that. But haven't played far enough in any of the GameCube games see it myself

abj

@mitu Yes i added this extension to es_system.cfg file but i have to find a save file from a multi-disk game to check if the changed will happen. Thanks.

abj

@retropieuser555 This is how i am changing the disk right now, and they suggesed me the same thing in the Dolphin discord server, It's working very well, the disk change automatically but this only works if you start the game from the Gui.

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.

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?

abj

@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).

abj

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'.
