Lately, several people have been publishing videos of themselves playing 3DS or Wii U AAA titles on their PS Vita, such as Pokémon Sun/Moon or Mario Kart 8. In most cases, the authors of the videos explain how they’ve done it. In some cases however, either the author of the video (intentionally or not) doesn’t explain the technique used, or other people use it to trick other people into believing the PS Vita can run 3DS or Wii U games, on its own. The truth is, yes, you can play 3DS and Wii U games on a hacked PS vita, but not directly.
How to play 3DS and Wii U games on a PS vita
You can play 3DS and Wii U games on a PS Vita, indirectly. In practice, you will be running a 3DS or Wii U emulator on your PC, and streaming the result to your PS Vita. Technically, the PS vita is used as a screen and a controller for the game, so, in practice, you are really playing these games on your PS Vita, but your PC does the actual work in the background. Awesome to play in your bed or on the couch, but this will not let you play Pokémon Sun on your PS Vita in the Bus.
It’s still an impressive feature, all thanks to the port of Moonlight to the PS Vita. This tool, which requires an NVidia graphics card, lets you stream the screen of your PC to any client, including the PS Vita (thanks to the port of the moonlight client)
