N64 Blast Corps artifacts

[Canniballistic]

I'm getting constant artifacting during gameplay and not in menu's.

Black flashing visual glitches.

Tried messing with the output method, none of them fixed it.

I did this on another game and it fixed it, so you could try this: Run the game using project 64, then copy the shaders and keys from: 'Ptoject64\plugin\graphics\GlideN64\shaders' and paste them in 'RetroArch\system\Mupen64Plus\shaders'
