Custom PPSSPP shaders

Anyway, I downloaded PPSSPP so that I could emulate Birth By Sleep (actually purchased Birth By Sleep on Amazon for the purpose).
As I played it, I realized there was one thing missing - when I played KH1 and 2, I played them on those old NTSC televisions. I wanted to replicate that feel as a post process shader, and I'm nearly there.
There is just one thing I need - is there any way to get some kind of time value in the shader? I want to scroll the scanlines over time, but have no idea how.
Any help?

Can't you just do some loop from top to bottom pixel until it reset back to top periodically? Not sure if that's what you want though.
