Language in PPSSPP & Games [Ubuntu 13.04 64bit]

[Iljalicious]

Hello guys!
I found your great emulator 2 days ago, and I'm totally impressed by your work.

Everything's working on my notebook, every game I own run in fullspeed (just without Sountracks, but that's not a deal for me).
I'm always using the latest build, right now v0.7.6-799-gc439796. (SDL)
(I wasnt able to compile the Qt-Version for some reason, but I want it so badly..)

I tried the ISO of Kingdom Hearts Birth by Sleep [EU],
it's working fine, but I cant change the language/region of the emulator.

I tried the emulator on my girlfriends tablet, I was able to choose the language, and the game's default settings were in german too, just not on the PC.

Can someone help me maybe? :3

Thanks in advice !
