Currently doing some demo coding experiments where I want to change the bitplane registers every line (yep, I'm sure you can guess the type of effect).

Anyway, I started out simple with just a single plane. What I wanted to do this time was put a wait in for the end each line rather than specifying the vertical position. However the result looks like its not waiting on every line?

This is an attempt to make copper programming a bit easier for me so I don't have to have massive lists specifying every vertical position!

I'm pretty sure I have the wait instruction correct?

Code:

_c_CRL		rept	256
		dc.w	$00e3,$80fe
		dc.w	bplpt,$0
		dc.w	bplpt+2,$0
		endr

Any ideas?
