A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .dat1 Files
.DAT1 files are binary data files used by the NeoRAGEx emulator for savestates. They store a snapshot of game data that lets you resume gameplay from a specific point.
They use the MIME type application/octet-stream, which is common for files containing raw binary information.
- Main use: Saving the current state of an emulated game.
- Operation: Created and read by the NeoRAGEx emulator.
- Technical Note: The generic MIME type means they are treated as binary files without a built-in file structure.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .dat1 file used for?
A .dat1 file is a savestate created by the NeoRAGEx emulator, a program used to play Neo Geo games on PC. It stores a snapshot of the game's memory, allowing players to resume their progress from the exact point where the file was created.
How do I open a .dat1 file?
You cannot open these files by double-clicking them. Instead, you must launch NeoRAGEx, start the specific game associated with the file, and use the emulator's Load State command (often mapped to a function key like F7 or accessible via the menu).
Can I edit a .dat1 file with a text editor?
No, .dat1 files contain raw binary data rather than plain text. Opening them in a program like Notepad will result in unreadable characters, and saving changes will likely corrupt the file, making the save unusable.
Why is the MIME type listed as application/octet-stream?
The MIME type application/octet-stream is a generic identifier for binary files that do not have a specific, standard text format. Since .dat1 files are proprietary binary dumps specific to NeoRAGEx, systems default to this generic type to handle the data safely.
Can I convert a .dat1 file to work with other emulators like MAME?
Generally, no. Savestates are highly specific to the emulator version and internal memory structure. To move progress between emulators, it is better to rely on in-game save points (SRAM) rather than emulator-specific savestates like .dat1.
Where should I save my .dat1 files?
For NeoRAGEx to recognize the save, the file usually needs to be in the States or Saves folder within the emulator's directory. Additionally, the filename (excluding the extension) must often match the name of the game ROM file.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
