Alright I would like to apologize as I know this got a lot of attention really fast, and I know it didn't work right away, but I have this proven build now, that works and plays. It's a good start, when I get my hands on a SD2Vita I will try to find the sweetspot between performance and graphical fidelity, aswell as ironing out bugs!
Oh and Android is finally signed, so you should be able to install and play it there too!
Enjoy!
