Wow, thank a lot! I'm gonna try this on 2d/3d games which are a hassle to emulate. I'm really quite enjoying the game now that the scanlines from crt-pi are hiding the jagged look of the 3d models without being too dark.You can edit the shader with an text editor (notepad++) or just with a simple windows editor and uncomment the define for curvature:
This shader has some other options that can be altered also...Code:
Another one which i like to use with "problematic - hard to enhance" games is 4xsoft + lottes mask, is very fast and looks pretty.
Best used with high (2x) internal resolution and screen smoothing, so 3D will get a boost also.
