Castlevania The Dracula X Chronicles US

[BouncingBreasts]

The windows version of ppsspp 0.9.9.1 runs fine.

but on Android using Asus Zenfone 5 there are problems :
- Symphony of the Night at title screen that shows me "Press start button" there are black plain squares at the bottom right and upper left corner of screen. They usually be the shadow of tree...
Also, while playing, I found some objects that are plain black squares too.

- **** The game itself (push "game start" at the dxc's title screen) had run with no problem until yesterday. Now whenever I push "game start", ppsspp always crashed while the game was saying "Now loading" and go back to app screen.
I really don't know what happened to my phone. It should run smoothly as before...... Do I need to clear cache or something ?
