.GGZ Bestandsextensie

NeptunJS is an online video game console emulator that integrates with other emulation software, to provide a multiplatform emulator. The emulator has its own website at NeptunJS.xyz, and it is integrated into other websites, such as RetroGames.cz and MyEmulator.online.

When a player presses the Download save state button while playing a game in NeptunJS, the game produces a GGZ file. This file contains a record of the player's in-progress game.

GGZ files are emulator-specific, meaning you can open a GGZ file only while using the emulator that created the file. The easiest way to open a GGZ file is to visit NeptunJS.xyz and navigate to the webpage used to play the video game from which your GGZ file was created. Begin playing the game, and then click the Load state button. Then, navigate to and open your GGZ file.

Can I use a GGZ file in non-NeptunJS emulators?

GGZ files are .GZ archives that contain a save state file and a .PNG preview image. If you decompress your GGZ file, you can use the save state file it contains to resume your game in a supported emulator. For example, if your GGZ file contains an .N64 file, you can decompress the GGZ file and then open the N64 file in Nemu64, OpenEmu, or N64oid.
