Extract text from emulator save states (ST0)
To convert ST0 save states to another format, you need VisualBoyAdvance or other Game software.
To convert other file formats to the "Emulation Data" file type, you need software like VisualBoyAdvance or a similar tool.
A .ST0 file is primarily a Save State (specifically Slot 0) created by older game emulators like VisualBoyAdvance (GBA) or VirtuaNES (NES). Unlike a native in-game save (Battery Save), which writes to the cartridge's SRAM, a .ST0 file captures a frozen snapshot of the emulator's entire Random Access Memory (RAM) at a specific millisecond.
Users typically encounter friction when trying to move progress from VisualBoyAdvance to modern emulators like RetroArch, mGBA, or hardware like the Analogue Pocket. Because .ST0 files are proprietary memory dumps (often GZIP compressed) rather than standard save files, simply renaming them to SAV will fail. To "convert" them effectively, you must typically load the state in the original emulator and perform a native in-game save to generate a compatible file.
In professional engineering contexts, a .ST0 file is an HSPICE simulation status file generated by Synopsys software. These are plain text logs used to debug circuit simulation failures.
Convert.Guru analyzes your ST0 file, detects the exact format, and lets you read the text inside.
Users also converted STO, GBA, CLT and ST1 files.
If you want to convert ST0 file to , you can use VisualBoyAdvance or similar software from the "Emulator Save State" category. In the File menu, look for Save As… or Export….
To convert files to ST0, try VisualBoyAdvance or another comparable tool in the "Emulator Save State" category.
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 ST0 converter.
