WinUAE doesn't hand over a bitmap to post-process freely? (Along the lines of, asking like a child gives results).
If a shader causes jitter, how is it a visual improvement? (Again with the offensively stupid questions
) It didn't get past the disk hand, and I didn't use a mask.
Well any shader that I can use should display the same picture, just with scanline emulation.
I'm not a heavy WinUAE user, I think it's just a difference between game eyecandy and something usable for text, creative use, etc. Different expectations. Game screenshots here are certainly not as intended/drawn. Which is kind of the point; everything looks better.
