Small tweaking to a fast crt shader

Hy guys,

so, i’m in over my head here. Could someone make a small modification to the crt-hyllian-fast.glsl shader? I tried but it’s really out of my skill set. It is an excellent shader for my aging (God damn it Cartman!) Galaxy S4. It looks great with Integer Scale OFF and it is >fast< BUT it is just a little too dark. So, could some parameters be altered to make it just a little brighter? SOmething along the lines of the default linear filtering gamma.

thank you!!

Hey, as far as a noob like me can tell the part you need to edit is at the end

_color = _color*_d; _TMP7 = pow(_color.x, 4.54545438E-01); _TMP8 = pow(_color.y, 4.54545438E-01); _TMP9 = pow(_color.z, 4.54545438E-01);

more than 4.54545438 is darker less than 4.54545438 is brighter

Thanks a lot man!

It works very well. I tested on Street Fighter 2 and this is how i remember the game looking at the arcades :smiley:
