Hi Grazey,

It's Tomchi's track "LTC 08 Sheep'n' Chip"(http://sndh.atari.org/sndh/sndh_lf/Tomchi/DMA/LTC_08_Sheep_n_Chip.sndh) - plays fine in XSC s I know the file is fine.

I do depack it first but it bombs out on me on replay...

Code:

jsr initialise init library
lea music,a0 load address of packed music file into address register 0
lea depack,a1 load address of buffer in which we are unpacking into address register 1
bsr ice_decrunch depack it, unpacked file will be in our buffer

bclr #0,$484 keyclick off
moveq.l #1,d0 tune 1
jsr depack start playback

*** Backup registers
move.l #backup,a0
move.l $70,(a0)+ backup vector $70 (VBL)
move.l $120,(a0)+ backup vector $120 (timer b)
move.b $fffa07,(a0)+ backup enable a
move.b $fffa13,(a0)+ backup mask a
move.b $fffa15,(a0)+ backup mask b
move.b $fffa1b,(a0)+ backup timer b control
move.b $fffa31,(a0)+ backup timer b data

move.l #vbl,$70.w hook VBL


wait cmp.b #57,$FFFFFC02 wait for space
bne.s wait

jsr depack+4 stop music
move.l #backup,a0
move.l (a0)+,$70 restore vector $70 (vbl)
move.l (a0)+,$120 restore vector $120 (timer b)
move.b (a0)+,$fffa07 restore enable a
move.b (a0)+,$fffa13 restore mask a
move.b (a0)+,$fffa15 restore mask b
move.b (a0)+,$fffa1b restore timer b control
move.b (a0)+,$fffa21 restore timer b data

jsr restore

clr.w -(sp) exit
trap #1

movem.l (sp)+,d0-d7/a0-a6 restore registers
move.w (sp)+,sr restore status register

jsr restore

clr.w -(sp) exit
trap #1


*** VBL Routine ***
vbl move.w #$700,$ffff8240 set the background/border to red for timing
jsr depack+8 music player
move.w #$000,$ffff8240 set the background/border back to black
rte

*** End of VBL ***

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
