PPSSPP 1.2.2

http://forums.ppsspp.org/showthread.php?tid=5236 -- this is the thread on performance.

There will be only so much you can do on your nokia x2 dual sim seeing as it is using a dual core snapdragon 200 with 512 mb of ram. On the plus side your screen's native resolution is low enough that anything over 2x is really wasting performance anyways. So try setting the psp and screen resolution to 1x and see if you can maybe get close to an ok framerate.
