Custom PPSSPP shaders

[LunaMoo]

Why don't you ask in Dolphin's forums? Here's a link.

I don't know anything about dolphin's post process shader support, but if it uses glsl, you could use my "custom aspect ratio"(it's in the first post, I just forgot to mention it in the list) shader as a base if that's what you need, it doesn't do zoom-in, but it should be trivial to modify it to just use X or Y scale instead of automatically picking as it does now, but you'll need to change the input and potentially formatting to match what dolphin uses. Possibly also remove options and replace them with hardcoded values if dolphin doesn't support post process settings and if it does, just rename them to what Dolphin recognizes.
