Wii games showing a black screen then closing right after

[Blexter]

The title says it all, I'm trying to launch some Wii games (Mario Galaxy 2 mainly) but as soon as I launch it, it shows me a black screen for a couple of seconds and then closes. I've tried in .ISO and in .WBFS but it still does not want to open, the Gamecube games work totally fine, they even have an image while the Wii ones don't... Please help me ! (I am using the latest version of the emulator)

First try changing your graphics backend.
If you are using OpenGL then change to Direct3D, or if you are using Direct3D then change to OpenGL.

If this doesn’t solve the issue then:-
Right click the game in the game list > Properties > Verify > Verify Integrity.
Then post the results here.
