I've just uploaded a couple of source files, though in practise notes.gen was constructed by a python script that parsed a siddump of the original tune.
Assemble with cl65 --cpu 6502X -o music.prg music.s -C c64-asm.cfg --start-addr 0x1000
The tune follows a pattern of ABAC, so the note table just contains BAC, and init starts the tune at A and enables a code fragment that resets the note index (ipc) to the start of B the first time the note index reaches the start of C.
Only five zero page locations are used; one note pointer, a loop control value, and three note duration timers. Gate is cleared three frames before the end of each note, as observed by eyeballing the siddump output of the original. |

So torn about which compo to enter this one into :D
Threw it together in under 24 hours - first working version was 310 bytes of code and data, final is 255. |
