how do you convert a gba rom to a psp rom?

Question

Please!!!!

Answer 1

you don't convert it

you need a gba emulator on the psp in order to play the gba rom

if you've ever upgraded your psp, you probably won't be able to do it, from what i've read

Answer 2

No need to convert rom. But you need an emulator to run GBA roms on PSP.

Also, your PSP has to be homebrews enabled in order to run the emulator.
