About .cjm Files
CJM files are plain text configuration files for TheC64 joystick and mode settings. They use the MIME type text/plain, which means the content is stored in simple text that any basic editor can open.
- Main Use: They record customized settings for TheC64 systems, often used in emulation or hardware configuration.
- Plain Text Format: Being text-based, these files can be viewed and modified with editors like Notepad.
- Configuration Details: They store parameters for joystick configurations and operational modes.
- Technical Note: The use of text/plain makes them easily portable across systems.
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 .cjm file used for?
A .cjm file is a configuration file specifically designed for TheC64 (Mini and Maxi) retro gaming consoles. It dictates how the system should emulate a specific game file, storing settings such as the preferred joystick port, screen mode (PAL/NTSC), and machine model (C64 or VIC-20).
How do I open and edit a CJM file?
Since CJM files are stored in a standard plain text format, you can view and edit them using any basic text editor. Common tools include Notepad on Windows, TextEdit on macOS, or Notepad++ for more advanced editing.
How do I make a CJM file work with my game?
For the console to recognize the configuration, the .cjm file must have the exact same name as the game file (e.g., GameName.d64 must be paired with GameName.cjm). Both files must be located in the same folder on your USB drive.
What is the MIME type for CJM files?
These files utilize the text/plain MIME type because they contain human-readable ASCII characters without binary formatting. For more details on how systems handle text files, you can visit mime-type.com or view the text/plain entry.
What settings can I put inside a CJM file?
You can define various flags such as J:1 or J:2 to set the primary joystick port, TV:PAL or TV:NTSC for display timing, and X:64 to force C64 mode. These parameters help ensure that games relying on specific hardware configurations run correctly.
Why is my CJM file not being detected?
Common issues include filename mismatches or the operating system appending a hidden .txt extension (resulting in filename.cjm.txt). Ensure file extensions are visible in your OS settings to verify the file ends strictly in .cjm.
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.
