For those of you worried that Sony might one day have a magic patch for all psp usermode exploits, frostegater has good news for you: Vita’s firmware 2.0 still has some holes in the PSP emu (screenshot below).
He proves it with a typical Hello world running inside the psp emulator of the Vita. It’s no surprise, as I mentioned before we still have dozens of game exploits available on the psp (and those are compatible with the psp emu on the Vita) – lots of which, I need to mention, were found by frostegater himself -, but it’s good to confirm that these undisclosed usermode exploits still run even after a release of a new Vita firmware.
