What is a .JST file?
The file extension .JST is associated with a JavaServer Page Document, but in this context, it is specifically used as a save file by Jnes, which is an emulator program for Windows computers. An emulator allows one computer system to behave like another system. Jnes is designed to emulate, or mimic, the Nintendo Entertainment System (NES), a popular video game console from the 1980s.
A .JST file contains a save state from a game that you are playing on the NES emulator. This means that the file saves the exact point in the game, including the game progress, the on-screen position, the inventory of the player, and any other details relevant to the game's current state. By saving this information in a .JST file, players can close the emulator and later resume the game from the exact point where they left off, without losing any progress.
To open a .JST file, you need to use the Jnes program. This is because the file is specifically created for and used by this emulator. When you want to continue playing your saved game, you open Jnes, load the .JST file, and the game will start from the save point contained within the file. This feature is particularly useful for games that do not have built-in save functions or for players who want to save their game at specific points not allowed by the game itself.
