Code:

	dbf d0,setbpl									; branch until all bitplanes are copied

	; load the copperlist into cop1lc
	lea mycopper,a0									; Copper address into s1
	move.l a0,COP1LCL(a6)								; and into the Cop1 register
	move.w	d0,COPJMP1(a6)

I haven't looked very hard at your code, but that "move.w d0,COPJMP1(a6)" doesn't look right to me (think about what d0 would contain at this point, immediately after finishing a dbf loop)" ?
