Name that (SID) tune

Back in January 1990 I bought the latest issue of Commodore Disk User for my beloved Commodore 64 and it had a cool new menu screen complete with music and scrolling text.  Oddly this only lasted for one issue and they reverted back to the static menu from the next issue.

Anyway, I really liked the SID tune.

I didn't know the name of the tune and hadn't found it in the High Voltage SID Collection (HVSC) so far.  As the collection contains over 48,000 files it's probably not surprising.

There's a fantastic tool called SID Known (sidknown.exe) by Wilfred Bos which will examine .prg files for known SID tunes by comparing the signature with hashes of the entire HVSC database.

Here's the tool in action on the .d64 disk image for Commodore Disk User 303.

1. First use the command line tool c1541 to extract the PRG file for the main menu from the disk image.
2. Run sidknown.exe (with the latest hash database) to check for matches.

Gotcha! It correctly matched the following SID tune...
