This may be the wrong place to put this topic. If so, I apologize.
Ok, so I'm trying to run FFVII on my PSP, with CFW 3.90m33-2. I got Popsloader (3.80m33) and 3.71 firmware to go with it. (Since I've heard that the game won't run past 3.71/3.72.) Anyway, extracted the ISO with MagicISO, converted it to EBOOT with PopstationGUI3, put it in a folder called FFVII, and ran it, and got that error message (topic title). So then I tried using CUE/BIN. Same message. Popsloader is enabled, but I haven't even gotten the menu for it.
Hmm...I also just noticed that MagicISO is an unregistered version, and says it can only do 300 MB. However, the ISO I extracted is 600, so...idk if that could be it.
Any help/thoughts would be greatly appreciated.
