I've been trying to get them to work for a bit now, but none of them seem to start. I've tried the gbsp thing that seems to be recommended a lot, but it doesn't start for me. I have 3.71M33-4 firmware on a fat PSP. I've been able to get PSX and PSP ISOs to work, but am not having luck with GBA stuff. I copy it into the PSP/GAME folder, and I can see it, but it encounters an error whenever I try to run it. The files I've tried come with a 1.5 version and another version, and I've tried both since I don't know the difference. Neither work. So yeah, I'm asking here now cause I've searched and followed instructions, but I must be doing something wrong cause it's not working. Any help would be great! On a sorta side note, after I get the GBA emu to work, I want to try a SNES one. Hints and stuff before I start searching would be awesome.
