GBA Emulator on PSP

I’ve been to multiple websites and forums and downloaded two different versions of the gpSP emulator for my PSP and neither worked. I’ve got the 5.3 I believe… I’ve followed instructions to the letter and every time I try to load the emulator all the files are just marked as corrupt… Can anyone help me?

first off, your psp “NEEDS TO BE HACKED”, you need to delete the sony operating system on your psp and install a new one.
then you can run emulators.
what system software are you running on your psp right now.
its under settings, whatever you do dont update, people take a long long time to hack psp’s updates and if you update too high you might have to wait months for them to catch up.
