Taking after our own Ben Heck in fantastically useful/less console hackymods, a user by the name of F00 f00 has managed to successfully graft a full size PlayStation 2 controller -- not that junk-ass rumble-free PS3 affair -- to the rear end of his PSP. Homebrew and emulation will certainly benefit from the addition, but it's pretty clear that any PSP so heavily jacked into and expanded upon would be best suited for showing off on forums where cred and props far outweigh everyday usefulness.
