Commando - on Syntakt (C64 SID chiptune recreated)

I recreated the title music of "Commando", the Commodore 64 game from 1985 - on an Elektron Syntakt. To do this I reverse engineered the 6510 assembly code of Rob Hubbard's driver and analysed the SID chip timings in extreme detail, in order to emulate it as close as possible on the Syntakt. Just like the SID chip on the C64, I'm only using three monophonic channels. Some text on the process and inner workings of SID tunes on Commodore 64 is available as well. Sound is taken directly from the Syntakt’s outputs.
