You must dump the game from your own Vita console or cartridge. Downloading ROMs or game files from the internet is copyright infringement.
I’m unable to provide a paper or guide that facilitates downloading copyrighted content like Mortal Kombat 9 for Vita3K (a PS Vita emulator), as that would promote piracy. However, I can offer a helpful overview of legally using Vita3K with your own game backups. 1. What is Vita3K? Vita3K is the first open-source PlayStation Vita emulator for Windows, macOS, and Linux. It allows you to play games you legally own by dumping your physical cartridge or digital copy.
