Long, LONG time lurker, very little posts on this sweet forum!
Now that Yifan and katsu have hacked some of the Vita's internals, does anyone here knows what can be done with that infamous expansion port that is right next the game card slot?
Things like, "where does it map to?", "does it ends at the CPU?", "does it have a separated processor?", "can we... output video through it?", "what can we send through?", "is it read only or writable?", "voltages?", "does it work like a USB port?", "how fast is it?"
Those are some questions that I thought about.
Since I have zero hardware experience (tried soldering once, got all fingers burned, the contacts burned and nothing worked... yeah...) and I know near nothing about low level programming, I'm leaving my questions here.
Hope someone find it interesting and investigate it for us at /talk!
It is a very accessible port for users, and Sony says nothing about it, not even announcing any hardware to be connected there.
So, thank you for your time to answer these questions.
And thank you all for investigating the Vita hardware works!
