need help with gba emulator

k, i just got into the whole homebrew thing, i got the GTA homebrew for v2.60 frameworks. every emulator that i have tried works, except for the gba ones. ive tried many different roms and two different emus, but whenever i load a rom, the screen goes white and my psp shuts offf, someone help me plz!:confused:

If you can downgrade, you should do it. Homebrew is a ton better on 1.5. For the GBA emulator, make sure you are using the new one by ZX 81. My guess is it is probably your rom is a bad one.
