A long time back I bought a 1.5 firmware PSP. But I have long since sold it... and I knew how to hack it too.. hooray for the MSD quick switch. Now, I want a PSP again, but i highly doubt that there are 1.5 floating around. Basically, my question is: Since I've been out of the loop for so long, What version of the PSP do I need so that i can hack its "fullest" potential. I'd be greatly obliged if I wasn't flamed...
Thanks!
