About SG1 files

The .sg1 file extension most commonly represents a Game Boy Advance savegame created by the VisualBoyAdvance emulator. It can also function as an S-57 Geodatabase file used by SevenCs for marine navigation, or a profile for Kisters 3DViewStation. Emulator save files are notoriously rigid. An .sg1 save state is essentially a raw memory dump of the console's RAM at an exact frame, often compressed using the standard GZIP algorithm. This creates extreme vendor lock-in. The file requires the exact same emulator version and the precise game ROM to load correctly. Attempting to move an .sg1 file to a different emulator, like mGBA, usually fails because the memory mapping differs. Similarly, S-57 database files are locked into proprietary GIS workflows. Converting an .sg1 save state directly to another format is rarely possible. The recommended workaround is to load the .sg1 file in the original emulator, save the game using the in-game save menu, and export the resulting battery save (sav format), which is widely supported across emulators. This file format is difficult to open or convert externally because it acts as a highly specific internal snapshot rather than a standardized document. Often, only the original software can properly read or export the data. However, you can drag and drop your file into convert.guru to see what it is and convert it if supported. Our deep-scan analysis can identify if your .sg1 file is actually an embedded GZIP archive, potentially allowing you to extract the raw internal content.

Convert.Guru analyzes your SG1 file, detects the exact format, and lets you read the text inside.

Users also converted ST1, CLT and GBA files.

The SG1 Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SG1 converter.
