Hi, try this:

  1. Open Citra then go to File->Open Citra Folder
  2. Open shaders folder then delete the opengl folder if it is there.

Utility_CustomTextures: true

Try turn off custom textures.

Done both, but nothing changed, it tries to load but then it gets stuck

Try disabling “disk shader cache” in emulation>graphics>utility.

Done it, still the same, by the way, I also installed another emulator (android) on my pc, does it have any sort of conflict with citra?

Not that I know of.
There’s not much I can think off that would cause your issues…
Could you maybe provide your GPU and CPU?

I don’t really understand about this stuff is this it?

I got this from the steam app

Let’s update your drivers first.
Download win64_15.33.51.5146.exe from
Direct link: win64_15.33.51.5146.exe

Then follow this guide to install it:

Lastly, because you have a troublesome GPU for citra, you want to be using an older version of citra.
Download citra-windows-mingw-20191214-ddb7ead.7z from
Direct link: citra-windows-mingw-20191214-ddb7ead.7z
After you’ve downloaded it, extract it using 7zip or winrar to anywhere you want. Inside the extracted folder you should find cita-qt.exe. Whilst the next step isn’t particularly necessary, it might be good to do in your case --> Create a folder called ‘‘user’’ in the same folder as citra-qt.exe. This will make citra create all the folders it usually creates in the default install location in that ‘‘user’’ folder instead. Meaning it will be a fresh intall (this also means your save won’t be there when you load your game).afbeelding
After you’ve done all that, run citra-qt from the folder and launch your game.

It’s working! Many thanks!!! I wonder what could’ve caused that problem though, also, does this mean that I cannot update the program and I should leave it as is, as long as it works? Again, many thanks and sorry for the trouble!

If you’re now using the nightly 1392 version, you should not update citra until you upgrade your hardware. Your current GPU is simply not very compatible with the latest citra versions. As for what might’ve caused your issues, could have be a lot of things. Could have been permission issues in Appdata (where citra usually stores game and config data) or maybe, like I already mentioned, your GPU didn’t wanna play nice with the latest citra versions. It’s probably not worth spending the time to figure out exactly what the original problem was.
