Technically I mentioned it first when I said emulators but I'll get other it hehehe I was gievn a broken PSP, fixed and left it then read up on all the modding you can do it it, fantastic piece of kit, even my bro wants one now, almost wants the PSPgo though, bad man!
Not gonna lie, i imaged all 3 FF disks and it took up just over 1.5gb... shiz imma need a new card or something. I miss my ps1! Just found my copy of coolborders 97 lol... that was a badass snowboarding game back in the day!
Coolboarders! I still have that somewhere, along with the original Crash Bandicoot, and Liberogrande, the worst football game of all time...
Monster Hunter Freedom, Wipeout Pulse, Warhammer 40,000: Squad Command, Little Big Planet, God Of War: Chains Of Olympus, Tekken Dark Ressurection, Jeanne D'Arc, Syphon Filter: Dark Mirror & all of the GTA games are all great games.
disgaea 1 and 2 are out on the psp with loads of extra content over the ps2 originals. There's also some cool puzzle games for psp like lumines, and power stone collection for some dreamcast goodness. As well as tekken and soul calibur there's street fighter and darkstalkers for some 2d alternatives. You can also use your psp as an ebook reader as well as everything else everyone has mentioned.
