A couple of hours ago, TheFlow, a well known Vita dev has teased a full eCFW for FW 3.60.
Adrenaline is going to be the ultimate eCFW for PSVita.
Forget ARK and TN-V/TN-X, this release will include support for graphics filtering, touch, dual analog and much more.
As per usual, it's required you have a 3.60 PS Vita with the HENkaku exploit and a PSP game (can be a Mini, Demo or full game)
There's no ETA on a release at this time.
Btw, for 6.61 Adrenaline you need to have at least ONE PSP Game from PSN on it. It can also be a demo.
Features that I am working in is dual analog stick, motion, touch, graphics filtering, savestate, psp/ps1 games loading
I have nearly reverse engineered all the main functions of the pspemu.
