This shader is almost perfect for older games (nes / snes / smd). Is it possible to remove the curvature of the screen? Unfortunately, this shader has no settings at all.

Idk if you still monitor this post but if you look down you'll see the code: "uv = curve( uv );" Remove that. you can even go another step further in removing the curve function.
