GpSP Help needed

Apologies for double posting, but I can't find any answers anywhere for this problem.

I managed to get a gba_bios.bin and now it says there's an error with my systembuttons.prx

Any ideas?

I've search all over the internet for help but no such luck.

I am using it on a 1.5 Psp.

I converted the file to a 1.5 pbp. So I am missing something?

I've copied all of the files that into the folder with the pbp etc. The systembuttons.prx is in the right place, so what is the problem?

I've even downloaded the file again and copied the systembuttons.prx into the folder but still no luck.:confused:
