What is an SG1 file?

SG1 files mostly belong to VisualBoyAdvance. SG1 files are used in two main ways. In many cases, they serve as a compressed game save file for Game Boy Advance games. The file uses GZIP compression to store game state data. Emulators, such as VisualBoyAdvance and BizHawk, read these files to restore progress.
In other applications, an SG1 file may hold a 3D profile used in 3DViewStation. This profile can also contain geometry data related to SeaGrid.

Game Save: Compressed with GZIP and used by emulators.

3D Profile: Stores configuration data for 3D tools.

FilExt.com tip: More details on the game save format can be found at NGEmu.
