What is an ST0 file?

Game Boy Advance Save File: ST0 files in this case use GZIP compression to store an emulator's save state. VisualBoyAdvance writes these files so players can resume their progress at the exact moment the save was made. For details, visit VisualBoyAdvance support.

NES Emulator Save State: Certain ST0 files capture the precise state of a NES game in the VirtuaNES emulator. They allow users to continue a game exactly where it was paused. More information is available at VirtuaNES webpage.

HSPICE Simulation Output: Other ST0 files serve as raw output data for HSPICE simulations. They store simulation results for circuit analysis. For further guidance, see Synopsys.

ST0 file format:

Every file has a defined file format, i.e. how the data is arranged in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the ST0 files:

ST0 is seldom used as a file extension and includes different formats for the applicable programs. The file formats most commonly found in ST0 files are:

• 65% of all ST0 files are using the well-known GZIP file format to store the data. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. These files are binary files, so they do not contain text, but only cryptic characters. The files are 11 KB to 98 KB in size, with a median of 54 KB. The file type was developed only in the last few years. Some examples of file names are Pokemon - Fire Red Version (U) (V1.1).st0. Files like these are sometimes connected to pokemon, fire, mario, super, edicion, emerald, zelda, fuego and spain.
• 15% of all ST0 files are VirtuaNES savestate files. They consist of illegible, cryptic characters. The files are often between 16 KB and 31 KB in size. The files contain the following words: REG DATA, VirtuaNES ST and RAM DATA. These files can be linked to bros.

The remaining 20% of all ST0 files are different files with different signatures. Files like these are sometimes linked to espanol, legend, ultra, blue or hack. If you want to find out what your ST0 file contains, drag and drop it onto this page.
