Sound Interface Device (SID) is a format that houses Commodore 64 and 128 music. It consists of a BASIC program or a block of machine code which writes data to the SID chip, the entry addresses of the block, the number of songs in the file, title, artist, year, publisher, speed and used SID model. At a minimum, SID players emulate the 6510 CPU and SID chip in order to playback the audio, but SID files can also be loaded and played on a real C64.

The overwhelming majority of SID files are mono, as one chip can produce only mono sound. Some music may rely on two or even three chips (so it's called 2SID/3SID), doubling or tripling the amount of channels to make available hard left/hard right sound or even add center track to them with 3SID. No known games use this ability, only some Commodore 64 demos.

From 1990 to 1994, Sundell and Birk developed a SID player for their Amiga demo The 100 Most Remembered 64 Game-Tunes and for their tool PlaySID. Originally, a SID tune was spread over 2 files. Due to popular demand, an one-file format was introduced in PlaySID V2.2. This was the first version of the SID format.

All Commodore 64 games and programs can have their audio ripped to SID format. SSI 2001 soundtracks theoretically can be logged/converted into it, though as for now there is no possible way to do it.


Missing

The majority of popular Commodore 64/128 games have their music ripped to SID format, but this list includes games that either don't have a rip, or have an incomplete rip:

How to Obtain

Ripping SID files requires an intimate knowledge of MOS 6502 machine code and the SID chip, but luckily, most popular Commodore 64 games already have their sound ripped to SID format and can be downloaded:
