Adrenaline by TheOfficialFlow is an application that houses the official PSP emulator built into the PS Vita system. You’ll be able to access the majority of the original PSP’s functions, which includes being able to play PSX backups at full speed and full compatibility with PSP homebrew. Adrenaline also comes with a few extra features like graphical filters and local multiplayer with Dualshock 3/4 support. Adrenaline is hands-down one of the best homebrew applications on the PS Vita and one of the main selling points for hacking the device.
