There's only one save, not sure why there are two folders, but I hope they help.
Test config: LY-F1 tablet (Allwinner A10 chipset - Cortex A8 @ 1 ghz, Mali 400, 512 MB RAM, 800x480, Android 4.1.1), ppsspp v0.7-13-ge3789a5. The game otherwise (and except for the sound) runs flawlessly with at least 30 fps.
It's worth mentioning that if I sleep the tablet or open another app then return to PPSSPP the UI ANR's (perhaps something related to Suspend/Resume events).
