Custom PPSSPP shaders

[guest.r]

Hey there! Corners are sortoff hard-coded into the shader, but they can be altered/removed.

You need to alter the corner value in the corner function:

Code:

float corner(vec2 coord)
  {
                coord = (coord - vec2(0.5)) * 1.0 + vec2(0.5);
                coord = min(coord, vec2(1.0)-coord) * vec2(1.0, 0.5666667);
                vec2 cdist = vec2(0.01);  // edit this value
                coord = (cdist - min(coord,cdist));
                float dist = sqrt(dot(coord,coord));
                return clamp((cdist.x-dist)*200.0,0.0, 1.0);
  }

to a lower value, but greater than 0.0 or the image would turn black.

Thanks for having fun...
