ive bin using IRshell and loading them off my PC with the USBhost but i cant figure out what im sapose to do with a .IMG file

Opening
seq01
seq02
seq03
ff9.img
sles_029.65
system.cnf

so yeah any help is appreciated...

also im new to the forums but ive bin using pspbrew for over a year
if any1 has a CSO or ISO file they could PM that would be great to, i really wanna play FFIX or FFVII whichever one is the best

I have both, FFIX happens to run like a dream, i was able to complete it on my PSP, FFVII however has script issues that the emulator doesn't seem to like.
Use the Popstation GUI you got with the Custom Firmware you have (to convert it into a readable EBOOT file) if that doesn't work then you'll need to download it through a torrent agent, just google that term. Sorry there are a few reasons I can't send the ISO or EBOOT's myself. I happen to own the games.

Well you can download the games in eboot or ISO form from unnamed places if you don't happen to own the game.
