Project64 saved game
File type: Emulator file
A pj1 file is a saved game-state file created by the Project64 Nintendo 64 emulator.
It stores the player's progress so the game can be resumed later in Project64.

The pj1 file extension is associated with Project64, a Nintendo 64 emulator for Microsoft Windows developed by the Project64 team.
A pj1 file contains saved game-state data, including the state of the emulated game when it was saved. It belongs to Project64's own saved-game system rather than being a Nintendo 64 game ROM.
The file is intended to be used with Project64 on Microsoft Windows. The same game and a compatible ROM are generally required to restore the saved state.
Open a pj1 file through Project64 on Microsoft Windows. Start the same Nintendo 64 game in the emulator, then use Project64's saved-game or load-state command to restore the file.
There is no standard conversion format for a pj1 file. It is a Project64 saved game-state file, so it cannot be meaningfully converted to a video, document, or Nintendo 64 ROM.
To preserve or move the progress, load the file in Project64 and save the state again using the emulator's own saved-game functions.
