Performance issues in Pokemon games

[forhonorandpizzas]

Audio glitches? Do they only occur with savestates, or does it just happen spontaneously?

As for shaders, I would like to make the shader interface closer to what RetroArch does so that you can more easily port RetroArch glsl shaders, but at the moment, there aren't really more shaders. And the xBR shader I ported is glitchy and not really that great; I need to port different ones.

Spontaneously. Here is a 1(:09)min audio recording: https://clyp.it/g4iwpcn3

I'm looking forward to the shaders improvements, thanks a lot!
