Problem with crt geom and N64

Hi, I was messing around with shaders, when I used crt geom on the mupen 64 core, the screen became all black, but the game was still running. Is there any reason for this? I really hope it’s a fixable problem.

Try adjusting the curvature settings and see if it comes back.

Does this happen with other cores or just mupen? Are you using increased internal resolution with that core?

Try the GLSL version of the shader if you are using CG.
