A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .rom Files
ROM files are used to store non-volatile memory data.
They come in two main types based on the MIME type.
When the MIME type is application/octet-stream, these files are binary data used for a Cloanto Amiga OS encrypted ROM. This means they hold encrypted firmware or boot routines meant for Amiga emulation. Programs like Amiga emulators (for example, WinUAE) may use them to simulate the original hardware.
When the MIME type is text/plain, the ROM is a Logisim memory image. This plain text file stores data that initializes simulated memory components in digital circuit designs. Logisim, a tool for designing and simulating circuits, reads these files to set up memory configurations.
- Cloanto Amiga OS encrypted ROM: A binary file used with Amiga OS emulators to load secure boot or system routines.
- Logisim memory image: A plain text file that supplies initial values for memory in circuit simulations.
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.

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.
