so i downloaded some games, some 7z some rar, and when i unzip them they give me a folder named PSP_GAME that has some files (png, pmf, sfo, at3 files) as well as two folders (SYSDIR and USRDIR). One of them has a BIN file in it that I would assume is the game. I tried turning that BIN into an ISO and running it...nothing doing! I tried dragging the whole thing into UMDGEN...nothing doing! what do i do!?
