A few months ago we released the Argentine Songbook Vol. 1 chipdisk. And recently we released its source code including:

  • Full source code (the assembly files + makefiles + everything…)
  • Full audio sources (the SidWizard files)

And we also wrote a tutorial about how write a chipdisk, including all the tricks that we used.

If you have doubts/questions about it, let us know!
