A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .psg Files
PSG files are files that may store audio chiptune data or planning strategy information.
In one use, these files follow the Extended-PSG chiptune format with the MIME type application/octet-stream. They hold binary data that programs use to recreate retro chiptune music. They are common in situations where enthusiasts create or play music inspired by vintage video game sound chips.
In another use, PSG files rely on the PlanAhead Strategy format with the MIME type text/xml. These files contain structured XML that stores planning or configuration details. They are designed to be opened by text editors or specific planning software to adjust strategy settings or design configurations.
Key facts and use cases include:
- Extended-PSG Format: Used for chiptune music creation, emulation of vintage sound hardware, and playback with specialized audio players.
- PlanAhead Strategy: Employed for planning, configuration, and data exchange in strategy tools and design software.
According to FilExt.com, the same file extension can have varied purposes depending on context.
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 are the two main types of PSG files?
There are two distinct formats using the .psg extension. The most common is the Extended-PSG format used for retro chiptune audio, often associated with the MIME type application/octet-stream. The second is the PlanAhead Strategy format, which stores configuration data in XML text.
How do I play a PSG audio file?
To play Extended-PSG chiptune files, you need a specialized audio player or a plugin that supports retro console emulation. Popular options include Audio Overload or Winamp with a chiptune input plugin. These programs emulate the original sound hardware to synthesize the audio in real-time.
How can I open a PlanAhead Strategy file?
Since PlanAhead Strategy files use the XML standard, you can open them with any text editor, such as Notepad++, Visual Studio Code, or the built-in Notepad on Windows. These files usually have the MIME type text/xml and contain human-readable configuration tags.
How do I tell which type of PSG file I have?
Try opening the file in a simple text editor like Notepad. If you see readable text starting with <xml> or configuration tags, it is a PlanAhead Strategy file. If the content appears as a mess of unreadable symbols and random characters, it is likely a binary Extended-PSG audio file.
Can I convert a PSG audio file to MP3?
Yes, but because the file contains instructions for a sound chip rather than recorded audio, you must "render" it first. Software like Foobar2000 (with the Game Emu Player component) or Audio Overload allows you to export the playback to standard formats like WAV or MP3.
What is the correct MIME type for .psg files?
The MIME type depends on the file's content. For binary chiptune files, the generic application/octet-stream is typically used. For strategy files based on XML, the correct type is text/xml. You can learn more about these types at mime-type.com.
Why does my media player fail to open a PSG file?
Standard media players like Windows Media Player do not natively support chiptune formats. You must install a specific codec, plugin, or use a dedicated player designed for video game music emulation to open these files.
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.
