What is .ZS9 file extension?
File saved by ZSNES, an SNES emulator for PCs; stores an emulated game save state that is stored in slot 9; used to store a snapshot of game progress; can be saved and loaded at any point during a game.
ZSNES provides numerous save states from 0 to 99 (file extensions .ZS0, .ZS1, .ZS2, and so on).
