Suddenly... (etc)

Closerized.

I sold it to some random dude on 8bc, before being scammed. (once and for all)

while I'm here, this is some timer friendly code to do the same thing:

sei

; init song
lda #$00
jsr $7000

; point hardware interrupt registers at our play routine
lda #<raster
sta $0314
lda #>raster
sta $0315
; set raster position (in this case, below bottom border on PAL machines)
lda #252                        
sta $d012                      
lda $d011
and #$7f                        
sta $d011                      
; init interrupts
lda #$7f                       
sta $dc0d
lda #$01                        
sta $d01a
lda $dc0d                     
; return to system now interrupts are running.

rts

; play routine, just calls a frame of the music and changes border colour so we have some visuals.
raster
dec $d020
jsr $7003
inc $d020
; ack interrupts
dec $d019
jmp $ea31
 

GoatTracker doesn't have a timer-enabled driver attached to it when you export.  (afaik, unless they added one in 2.x series)

$7000 will init the song
$7003 will play a frame of the song only.

So you'd need a little bit of code to play it like:

SEI
; init
LDA #$00
JSR $7000
; loop, wait for raster ($d012) to hit line 128
RASTER LDA $D012
CMP #$80
BNE RASTER
; play frame of song
JSR $7003
; jump back to raster loop
JMP RASTER

hmmm.....

lately we should rename this place chipwhine.org
