I have a PSP 3000 and it runs openbor games just fine. I also find it extremely easy to hack. All you need is to downgrade it and get whatever firmware you want that works with the system. You might want a PSP 1000 because it is the only one that can play Mugen, which is a cool bonus. But its way harder to hack. I'd say that the PSP Go is the best one to get. idk what games will run or not, but it has 16 gigs of internal storage. I DO NOT reccommend using an Android instead because touch screens suck for games like bor. You need that nice fast(and accurate) response you can only get from buttons. And running that PSP emu on Android isn't as good as an actual system. if you must have an android though, get the Xperia Play, its basically a PSP android phone with PS buttons.
