Vita3K is a free, open source, multi-platform PlayStation Vita emulator capable of running PSVita games on a PC.
This emulator was developed by a group of volunteers to provide a PS Vita gaming experience without hardware limitations. It supports most PSVita games and can provide high-quality game running experience.
The simulator is constantly being updated and improved to provide more complete functions and performance. For example, in a recent update, Vita3K added support for the Vulkan rendering API, which has resulted in a significant performance boost for the emulator on some systems.
Note that since this emulator is still in development, there may be instances where some games will not run properly, or perform poorly on certain systems. However, if you have a strong interest in PSVita games, then this emulator is worth a try.
