Hi all, I am considering buying a Vita. Here are some questions: 1) Do I have to worry about fw version? Or are all of them hackable? 2) Do I need any extra tools to hack it or can it all be done with software? 3) Can Vita play PSP games once hacked? And I mean natively (without compromises like low framerate) 4) Can Vita emulate any of the more recent consoles (like PS2)? 5) Whats a good price for a new Vita these days? Thanks!
