I'm glad you like it and that it turned out well. I also think Lottes works very well with Amiga games, perhaps even better then on SNES ones for example.
Yep, Dosbox also likes CRT shaders, maybe not all games, but quite lot of it.
You can give this shader a try with Daum, should do well.
Normal2x scaler is to be used with it.
Curvature dosen't work though, no way around that.
@nobody: you are welcome and yea the previous crt shaders have a bid bugged shadowmask.
Edit: small fix to the shader.
Edit2: Another fix, scaler should be set to
none now.
