Homebrew and emulators are possible on the PS Vita thanks to the Rejuvenate hack. This hack gives access to the native performance and functionality of the PS Vita, rather than running on the PSP emulator which is constrained to the performance of the original PSP.
The hack has the following requirements:
- 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
- You need the PSM Dev Assistant for Unity on your Vita. If you have the PSM Dev Assistant installed on your PS Vita, this will work too.
- You also need a developer license from PSM+.
