I think I have the psp fat version 3.11. I say that because Im just barrowing it for a few days, and Im unsure off all the versions...lol I just wanted to know what custom firmware I need to install on this unit to make it work for back ups? Thank you for any help.
For backed up ISO's, you can use the newest (6.35) official firmware with the new HEN, but it is probably best to use Dark Alex's 5.00 M33-6 custom firmware.
