Problem with GBA emus and roms

Hi... I have a psp v2.0 with a eboot v0.9. I loaded in the new gba emu (the one with the incredibles on it) because when i tried the first one, it wouldn't start up. The newer emu starts up and takes me to the place where I can pick the rom. When i click on the rom, nothing happens and the screen stays the same. What am i doing wrong? Is there an alternate gba emu I can use?

no u just have to downgrade to 1.5 or just not use gba emu at all

Thanks, I successfullly downgraded with PSPortable's safe downgrade files and got it to work... Thanks for your help.
