This makes a fantastic result for both Pure and Pulse on both PSVita and PSTV.
It is pretty much un upscaler that makes PSP titles render in the native PSVita resolution instead of the PSP resolution! 960x544 instead of 480x272.
I'm using the latest release, 0.20. It has the advantage that if you want to play a game that is not compatible with ge_patch you can simply hold L when starting the game and the plugin will be disregarded. Download:

Here is a compatibility chart:

Green and yellow is good. Orange and red is bad. Overall compatibility is pretty bad unfortunately but Pure and Pulse have very similar behaviour. Only a few minor graphical glitches and some flickering when saving ghost files.
