PlayStation Vita, Sony, 2011.
whichemulator.wtf calls its recommendation for each system the Gold Cartridge pick. For the PS Vita, the Gold Cartridge pick is Vita3K.
Vita3K is the only Vita emulator that plays commercial games, so the choice makes itself. It's been in development since around 2018 and runs a decent chunk of the library, including some of the big ones like Persona 4 Golden. Expect plenty of games to still fall short.
Runs on Windows · Mac · Linux · Android. Open source. Download: https://vita3k.org
Firmware required: Vita3K needs the PS Vita system software, which Sony still hosts on its own site, plus the separate fonts package. Install both from the File menu before loading games.
Check compatibility first: Look your game up on Vita3K's compatibility list before you start. Many titles only reach menus or intros.
No other PS Vita emulator is worth recommending right now. If Vita3K can't run something, nothing else will either.
There is no Vita core.
Vita3K isn’t new. The slow progress is down to the hardware: a multi-core ARM chip, a tile-based PowerVR GPU and a full operating system with a lot of services games expect to talk to. Every one of those has to be reimplemented, and the team is small.
That said, a good number of commercial games are fully playable, and most homebrew runs. It’s worth a try, just check the list first.
RPCS3 once dabbled in Vita support and dropped it. Vita2hos runs on a Switch and only handles simple test homebrew. If a game doesn’t work in Vita3K, the realistic option is a real Vita, which is cheap to modify and runs everything.
