Flip GBA emulator or HTC tilt 2

[mastercats]

So I have a Tilt two, and i was wondering if there is anyway i can either flip the gba emulator screen or flip the UI on my tilt.

The reason i need this done is i got the tilt 2 mainly because it has a keyboard so i can play games, but the screen when set to full screen or vertical the game is flipped in the wrong way so that when i have the keyboard open it is upside down.

That or if anyone has a tilt 2 or knows of emulators that might work better for my issue that would be awesome.
