The video shows a PlayStation Vita running the Genesis game Sonic & Knuckles. Before you get too excited, note that the emulator isn’ perfect and it sounds choppy.
The emulator that you see running the game is actually being run by the Vita’s own PSP emulator.
Youtuber frwololo states that, “Sony put into place some security that will basically make this exploit moot as soon as it is made available, so this is just useful for research right now,”
This might be the start of hacking the PS Vita entirely and running homebrew on it smoothly.
