Davee, who got a PSP HEN running on the PS Vita with the help of devs Some1 and Proxima, is now studying the internals of the PSP Emulator on the Vita. In particular, he is looking at a library called sceKermit, specific to the PS Vita, which is in charge, among other things, of letting the emulator communicate with the PS Vita hardware.
Davee (as well, I assume, as proxima and some1) has been busy looking into this, and reverse engineered most of that API. For those not-so technical savvy among us, one goal I can see here (besides the pure technical interest), is that Kermit is currently “our” only entry point to the actual Vita hardware (per opposition to a tool like VHBL, which is sandboxed in the user mode of the psp emulator). Of course, given how simple that API sounds according to Davee’s description/code, it’s doubtful we will learn a lot from it… I’d say it’s a bit like trying to guess what a post office looks like just by looking at a mailbox…
That API is, however, the closest someone has been (publicly) approaching the Vita itself. Juicy details and source code, for those interested, on Davee’s blog here.
There is no plan from Davee to release the PSP Kernel exploit for now, so don’t ask
Oh, let’s have a game, what do you think “Kermit” stands for? If it’s not an acronym, why do you think Sony chose that name?
