.FRZ File Extension

An FRZ file is a video game save state created by Snes9x, an emulator for the Super Nintendo Entertainment System (SNES). It contains a snapshot of a player's game progress. FRZ files are used to "freeze" and "defrost" emulated game states.

Video game console emulators allow you to play console games on your PC. If you want to save your progress while playing a game in Snes9x, you can do so by selecting File → Save Game Position from the program's menu bar. This saves your current game state as an FRZ file.

It is also possible to produce FRZ files without Snes9x. For example, Wii gamers who use Snes9xGX to play SNES games on their Wii consoles can save FRZ files, which can be transferred to the PC version of Snes9x.

NOTE: Some versions of the Nestopia emulator also produce and open FRZ files.

You can open an FRZ file in Snes9x (cross-platform) alongside an accompanying game ROM (such as an .SMC file). To do so:

1. Place your FRZ file in Snes9x's Saves directory.
2. Open Snes9x and load your game ROM.
3. Select File → Load Game Position → Select File.
4. Navigate to and open your FRZ file.

The save state your FRZ file contains will appear in Snes9x.

Remember, if you are using Snes9x on Windows, you must rename the .frz file extension to .000, .001, etc. before attempting to open your FRZ file.
