Native homebrew and emulators are now a possibility on the PS Vita through the Rejuvenate hack. This hack gives us access to the native performance and functionality of the PS Vita, per opposition to the so called “ePSP” hacks, which ran through the PSP emulator on the PS Vita, and were constrained to the performance of the original PSP.
What is Rejuvenate?
Rejuvenate is a combination of hacks + tools on the PS Vita allowing people to run unsigned code (homebrews) on the PS Vita. It requires a PS Vita with Firmware 3.51 or less.
How to Install Rejuvenate PS Vita?
Make sure your PS Vita is on firmware 3.51 or lower. If you have firmware 3.52 or higher, your PS Vita cannot run the Rejuvenate hack
