What is a ZS4 file?

Zs4 file extension has ZSNES Slot 4 Saved State file type, developed by ZSNES, which is associated with the "game files" category.

This is one of the save file types used by ZNES, a computer emulator for Super Nintendo Entertainment System. The ZSNES emulator creates files with this extension to save player’s progress. You can load one of them to continue playing from where you have left. ZNES provides a hundred slots for saving (from 0 to 99) and changes the extension for each new save – the first one is .ZS0, the second is .ZS1, and up to .ZS99. There is a difference between ZNES save files and in-game saves. Original SNES games save your progress at set checkpoints or levels, while ZNES allows you to do it whenever you feel like it.
