Mario Kart DS (Europe) music and control glitches

[dankcuddlybear]

Some music sound channels are louder than others.

When I press R, instead of drifting the top screen goes black and then both screens have a white rectangle on them. When I press R again the pause menu appears, and I can hear part of the music. If I use interpreter instead of JIT the same thing happens except both screens go completely white.

I am using the Desmume Retroarch core, version 6343-1 (the latest) on Arch Linux x86_64.
