That's another (older) type, consisting of two separate files: The pure C-64
binary and an textual infofile containing metadata like name, number of
A newer format, called "PSID" was created some years ago which combines
these into one file.
The appropriate line of magic.mime would be:
0 string PSID audio/prs.sid
This doesn't catch all SID-tunes, though. Many are compressed with an old
compression scheme called "Power Packer" and have "PP20" at the beginning.
However, there are other files using that compression scheme, and you can't
extract the real contents from it, so this could be two other
0 string SIDPLAY\ INFOFILE application/sidplay-info
0 string PP20 application/x-powerpacker
