File TypeZSNES Slot 9 Saved State File
What is a ZS9 file?
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.
NOTE: A ZSNES save state is not the same as an in-game save state. A game only allows players to save state when arriving at specific game milestones whereas ZSNES save states can be captured at any time during gameplay.
