Custom PPSSPP shaders

[Nick001]

OK so I got around to fixing it, it now works properly with games that had issues before, but you can still set the amount of scanlines manually.

I also put in what I think is a fairly accurate* interlace simulation using u_time, however apparently you cannot have a 60hz animated shader in a 30fps game, or 30fps sections in some games like the menus in Wipeout Pulse (I tried u_time.x, y, z and w and this was the case with all of them). So in those games it just looks hideous. It's optional and completely off by default, so check out the config if anyone wants to try it.

I'm guessing it would be pretty unfeasible to make it work otherwise, right?

Anyway, here's the files:

And here's some screens of RR2 during a race!

BTW, was the rear view mirror in RR2 always broken? Or is that a new bug?

*(Edit: turns out it wasn't as accurate as I thought, since console games at this resolution managed to prevent interlacing. Oh well, it still kinda looks alright for a CRT-ish look without having to resort to 30hz on-and-off fullscreen flicker.)
(Edit again: having actually gotten my facts straight on this, it seems it may be accurate after all, because the anti-interlace trick that old consoles did only works for a maximum of 224 lines, while the PSP has 272. Not that any home console would use this resolution, so this simulation is kinda weird anyway. But again, it's about the general feel of the thing ).
