The only reason i want this is because i want to develop games and stuff for the Vita but the problem is i don't know how to code. And due to lack of any sort tutorial or a beginners guide I'm completely lost. But i do know how to use Unity.
Initial reply does not answer the question, I am also interested in whether anything has changed with 3.60, and if henkaku opens the door to developing and debugging unity on a real machine without having to go through Sony.
If you have a game on there you can do the patch trick like the undubs, but I gonna guess that you don't.
Your best bet for learning to program games for the vita would be to use Lua Player+ as Lua is an easy language to learn and it is a great start to getting your head around programming syntax. Plenty of lua tutorials are available online.
