And before anyone asks how you play 60Hz or other frequencies on 200Hz timer-c. It's not 100% accurate, but I doubt anyone could tell this from the real thing without knowing which is which.
Same init/exit stuff as before, and a little alteration in the code:
replay_freq: equ 60
my_c:
sub.w #replay_freq,timing
bpl.s not_yet
add.w #200,timing
movem.l d0-a6,-(sp)
jsr playmusic
movem.l (sp)+,d0-a6
.not_yet:
move.l save_c,-(sp)
rts
.timing: dc.w 200

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
