Davee probes deeper into the PS Vita’s hardware finds sceKermit
PSP/PSV developer Davee who recently posted a working PS Vita PSP HENvideo has started his work on studying the internals of the PS Vita’s PSP emulator. He has begun looking in details at the PS Vita library called sceKermit, this library is PS Vita specific and lets the PS Vita PSP emulator communicate with the PS Vita hardware. Davee and the team are working on reverse engineering the API, and at this stage this is the only point of entry to the PS Vita’s hardware. And whats learnt could be useful in the PSV’s future if the kernel exploit Davee has is ever released. (NO word on that yet)
Kermit is here so that the emu can communicate to the host to share resources and other vitality. Perhaps the primary reason is that of hardware; the PSP emu is excluded from many hardware devices. So kermit sets in and allows the system to talk to the vita in order to use the hardware. Blabbering aside, this is the hardware that kermit seems to be responsible for:
- Memory stick
- Flash filesystem
- Power Control
- … more
Interestingly, the kermit communication isn’t used for headphone remote or controller inputs.
In order to understand how kermit functions, it’s important to explore the usage of the API
Davee goes into some detail on sceKermit, you can read more over on his blog.
