JIT is now implemented (thanks to xerpi)
You can now select which rom you want to launch (albeit roms must be placed inside ux0:/data/desmume)
Launching a rom with the cross (X) button will launch the game with JIT enabled.
Launching a rom with the square ([ ]) button will launch the game with JIT disabled.
During gameplay you can press Select + Down + Left Trigger + Right Trigger to close the emulator.
