Port of PPSSPP to the OpenPandora

[ptitSeb]

I confirm it's not the CPU that make the games slow. I tried with "Puzzle Bubble", a game with no 3D. It's a bit slow on the Pandora. A openned, while playing, a SSH Terminal and launch "top" to see CPU consuption. And it is between 42% to 45%. So CPU is now underused. Sound is ON, I used VBA and Buffer for rendenring, and Fastmem for JIT.
I'll do the same with JIT disabled and report here.
