What is .ZST file extension?
Game file saved by ZSNES, a Super Nintendo emulator for Windows and Linux; stores game progress in a saved state so that the game can be opened and resumed at a later time; now also supported by the Snes9x emulator.
NOTE: ZSNES provides numerous save states from 0 to 99, which use the file extensions .ZS1, .ZS2, and so on, for each save state. The files can be saved using the "Save State" option under the "Game" menu.
