Mess with the "1.5" value on line 44,
color.a = clamp(1.5 - color.a, 0, 1);
It is sensitive, try .1 increments
Thanks! I think a 1.3 value is pretty good. Raster games never had much bloom. You could see a good amout of bloom in old arcade vector games.

I forgot to mention, this shader works best in lores mode. Otherwise, if the source is prescaled, you don't get much if any smoothing. That is, if you like that.
Sadly lores only is a limitation since some games/demos uses mixed lores/hires. The smoothing/blur is good enough in WinUAE hires mode+your shader imo. Great colors, matches older CRTs pretty good.
