So, my friend got my PSP to "3.80 M33-5" I have no clue, wth that stands for, but says it is custom firmware. So, i asked him, to download a few games on it. It worked, so i wanted to try it myself. Not that this is a Fat PSP, if that matters. So, i know in GBATemp giving a LINK to a download ROM/Iso is illegal. Im not asking for a link. But anyway, if i do get a game, i downloaded it, now what?
