Errors in KDE

[Amnesia1000]

At the moment the 3DS, Wii and GameCube games, when opening the properties tab, Rom-properties does not appear, but a tab that says xattrs. Besides not showing the thumbnails (which were successfully downloaded).

I'm currently using Manjaro KDE (Plasma 5.27.6 - Framework 5.107.0)

The games are fine, since Windows takes them well and displays the thumbnails correctly.

And on the other hand, when entering "kbuildsycoca5 --noincremental" it gives the following error:
kbuildsycoca5 running .... kf.service.services: The desktop entry file "/usr/share/applications/org.freedesktop.Xwayland.desktop" has Type= "Application" but no Exec line kf.service.sycoca: Invalid Service : "/usr/share/applications/org.freedesktop.Xwayland.desktop"

The xattrs tab is a new feature being introduced in rom-properties v2.2.

Are you able to do a git bisect to figure out which commit broke this? (It seems to be working fine here.)

[Amnesia1000]

Sorry, it is an error that appeared on the PC of a friend when trying to install rom-properties, and until yesterday I was at home, before I left I uninstalled it so that it would not create problems. I currently use Gnome so I can not reproduce the problem.

Could it be because it has KDE plasma 5.27 and KDE 6?

[GerbilSoft]

I'm using KDE Plasma 5.27 on my own system, so that shouldn't be a problem.

KDE 6 isn't released yet. There's preliminary support for it, but I could see that potentially being an issue if some early KDE 6 packages are installed.

[Amnesia1000]

Sorry, I meant to say QT6 not KDE 6.

[GerbilSoft]

Qt6 is only used if the necessary KDE Frameworks 6 packages are found. If not, then it'll use Qt5, since that's what KF5 uses.

[Amnesia1000]

Ok, then I don't know what it could be, I installed it normally as I installed it before in KDE, you can close it if you want, if I ever travel again and I can give more information about the error I will do it without problem.

I have the same error and I am using Arch Linux + KDE Plasma 5.27.7, I checked that in Thunar it works well with 3DS ROMs but in Dolphin it doesn't.

I should add that I have installed the rom-properties package from the AUR, I am the current maintainer of the package.

[GerbilSoft]

This may be related to the changes to use the newer JSON plugin loading system introduced in KF5 5.89. I'll need to set up Manjaro and Arch VMs to see if I can reproduce it there.

EDIT: Here's an easy way to test. In src/kde/kf5/CMakeLists.txt, find the line that has this:

SET(HAVE_JSON_PLUGIN_LOADER 1)

and comment it out. (Add a # character at the beginning of the line.) Then rebuild and reinstall. (Remember to set -DCMAKE_INSTALL_PREFIX=/usr .)

[dnmodder]

Well I wanted to give it a try but now I have a compile error that has to do with gdkpixbuf and gtk4.

[dnmodder]

Ah, compiling from master does not give me the error.

[GerbilSoft]

That particular issue was fixed in commit 348adc1 and was caused by the GTK devs moving gdkpixbuf.h to deprecated in GTK 4.12.

I'll eventually need to replace GdkPixbuf with something else, but I'm not sure what.

[dnmodder]

I applied that patch to fix the build in the PKGBUILD and also the commenting out the line of code in CMakeLists.txt and the tab still doesn't show up in Dolphin with 3DS games.

[dnmodder]

I originally forgot to say that with Wii and Gamecube games I don't have that problem, only with 3DS ones.

[GerbilSoft]

What MIME type does Dolphin say the 3DS games are? (Also the mimetype command line tool, in case they differ.)

[dnmodder]

application/x-ctr-cci and application/x-nintendo-3ds-rom

[dnmodder]

xdg-mime query filetype tells me it is application/x-ctr-cci

[dnmodder]

Also, I have a 3DS (MiiMaker) .app file, it tells me that it is application/x-nintendo-3ds-ncch in Dolphin and with the xdg-mime command, with that ROM the ROM Properties tab is shown.

[dnmodder]

Another thing, if I change the .3ds extension to .app, the ROM Properties tab appears. And xdg-mime returns this: application/x-nintendo-3ds-rom

[GerbilSoft]

application/x-ctr-cci is the issue. This MIME type appears to be specific to Citra; both rom-properties and upstream shared-mime-info use application/x-nintendo-3ds-rom.

I'll add Citra's MIME types to rom-properties to improve support.

[dnmodder]

I thought removing the .3ds extension from there would fix it but no.

[GerbilSoft]

Please try the latest commit from the master branch. Note that you will need to do a clean build because CMake doesn't easily let me add a dependency for the generated .desktop and .json files due to how it's generated.

Remember to run kbuildsycoca5 after installing.

[dnmodder]

I confirm that it works correctly.

[dnmodder]

I have created a new package in AUR so that other users can test it.
