A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .inp Files
INP files are binary files used by the MAME arcade emulator to capture and replay user input. They store the record of actions like button presses and joystick movements in a structured, compact way.
The file uses a MIME type of application/octet-stream. This indicates it is a raw binary file that isn’t formatted for text reading. The extended header in the file holds extra metadata such as timing and configuration details.
- Main Use Case: Recording and replaying arcade game inputs within MAME.
- Extended Header: Contains additional data needed for accurate emulation.
- Binary Format: Utilizes application/octet-stream for efficient data storage.
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
How do I open an INP file?
You cannot simply double-click an INP file to open it. You must launch it using the MAME emulator via the command line, typically using the syntax mame gamename -playback recording.inp. You must also possess the specific arcade game ROM that corresponds to the recording.
Can I convert an INP file to MP4 or AVI?
You cannot directly convert an INP file because it contains controller inputs rather than video data. To create a video, you must play the file back within MAME and simultaneously use the -aviwrite command or screen recording software like OBS Studio to capture the output.
Why does my INP file playback desync or fail?
Playback errors usually occur when the version of MAME used to record the file does not match the version used to play it. Emulation timing changes between versions, meaning an INP recorded on MAME 0.106 will likely fail on MAME 0.260.
Is an INP file a video file?
No, it is a binary recording of keystrokes, joystick movements, and timing data. It requires the original game engine (the emulator and the ROM) to render the visuals in real-time based on the recorded instructions.
What is the MIME type for INP files?
These files are classified as generic binary data, so they utilize the application/octet-stream MIME type. This designation indicates to web servers and browsers that the file should be downloaded rather than displayed as text.
Can I edit an INP file with a text editor?
No, MAME INP files are stored in a binary format. Opening them in a text editor like Notepad will display unreadable symbols; you would need a hex editor to view the raw data, though modifying it manually often corrupts the playback.
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.
