What is a ZS2 file? A ZS2 file is a save state created by ZSNES, a Super Nintendo Entertainment System (SNES) emulator . It contains a snapshot of a game at a specific moment in time, capturing the full emulated system state in a binary format. ZS2 files include memory and processor data, so the game can resume exactly where it was when the save state was created.

More Information ZSNES supports multiple numbered save slots, typically ranging from .ZS0 through ZS99, allowing users to maintain several separate save points for the same game. The .zs2 extension indicates that the file belongs to save slot 2. Players, speedrunners, and retro gaming enthusiasts use these files to preserve progress, retry difficult sections, or experiment with different outcomes without affecting other saves. Users can create ZS2 files at almost any point during gameplay using the emulator’s Save State feature.
