About .ch$ Files
CH$ files are binary files that store ZX Spectrum CHR$ bitmap data.
They contain character-based graphics from the classic ZX Spectrum computers.
The MIME type application/octet-stream means the file holds raw binary data.
- Retro Computing: Used by enthusiasts to preserve vintage game graphics.
- Emulation: Loaded by ZX Spectrum emulators to display original screen designs.
- Graphics Editing: Handled by specialized tools that edit or convert retro bitmap data.

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 .ch$ file?
A .ch$ file is a data file containing ZX Spectrum character bitmap graphics. It stores raw binary data representing 8x8 pixel blocks, often used for fonts or sprites in vintage software and retro computing projects.
How do I open a .ch$ file?
You need software capable of interpreting ZX Spectrum graphics formats. Specialized retro graphics editors like ZX-Paintbrush or SevenuP are designed to open, view, and modify these files, while some emulators like Fuse may load them as raw memory data.
Can I convert .ch$ files to standard images like PNG?
Yes, you can convert them using retro graphics tools. Programs like ZX-Paintbrush allow you to import the raw .ch$ binary data and export the sprites or fonts as BMP, GIF, or PNG files for use on modern systems.
Why does the file name end with a dollar sign ($)?
The $ symbol in .ch$ typically references the ZX Spectrum BASIC command CHR$, which relates to character data. It is a naming convention used by enthusiasts and archiving tools to indicate that the file holds raw character graphics data.
Is a .ch$ file a text file?
No, it is a binary file. If you open it in a text editor like Notepad, you will only see garbled characters because the content corresponds to the MIME type application/octet-stream, not readable text.
How do I serve .ch$ files on a website?
Since these are non-standard binary files, you should configure your web server to send the application/octet-stream MIME type. This ensures browsers treat the file as a download rather than attempting to render it as text or an image.
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.
