Shin Megami Tensei: Persona 3 Portable

[Fideon]

Hello everybody. I'm playing P3P currently and it's really smooth great work to the devs! The only problem that presents every once in a while is crashing when navigating Tartarus. This part of the game is on 3D, the emulator suddenly stops and exits without any warning or messages. Because of this I always save state after fights (the fights are on 3D too but the problem has never presented during a fight) immediately as I go back to navigating Tartarus. This problem (crashing) has even presented as I tried to save state after a fight, in the PPSSPP UI, it corrupted the save state. Fortunately I also save in-game as often as I can. so I didn't lose much progress.

My device is a Samsung Galaxy SIII i9300 (international)
It's running OmegaROM 4.1.2

I have the latest PPSSPP version installed (0.9.7.2)

Are there any settings crucial to the game's stability I should change?
I have also noticed that this ROM consumes a nice amount of RAM (I'm often at ~700MB out of 830 or something), should I upgrade my Android version to a different ROM running 4.3?

Again, thanks to the devs for such amazing emulator! You da bess.
