Custom PPSSPP shaders

[LunaMoo]

@bdszoke why don't you experiment? Just open ppsspp in a window, open shader in notepad or any editor you're using to edit it, and after you make your change and save it, it's enough to resize the window, switch to fullscreen/back or change anything else that works to refresh the shader instantly.:] If you have problem understanding some function like clamp or dot you could just check directly here, everything else is just a math.


=========================


Anyway I just looked here to say I reuploaded my shader with new preset for shadeboost which can also be done as very simple shader as I posted earlier in here which basically makes the colors colder to appear as on older psp screens, based on a picture of real psp from that issue.
At the same time I also fixed shadeboost, I guess nobody who used my shader really messed with colors since apparently the color part was broken(stupidly I used it only in a way which was accidently giving expected result;o) I was probably tired while adding it or something, blah;p, also simplified a bit the variables there.

Here's a small comparism of colors normally in ppsspp:
   
and with the psp colors(or rather old psp colors, since psp 3000 had better display)
   

It's strange, but for some reason many games seem to look quite nice with it, not sure if it's because of my personal prefference to colder/bluish colors or because many of those games were designed to be displayed for those old psp screens and end up too warm/dark otherwise, but I'll probably be using it for more games myself now:].
