Re: hbl on falcon

Why do it like this in the first place? The first thing I'd try myself is to make my own screen pointer book-keeping instead of trusting the video counter:

my_hbl: andi.w #1,counter
beq.b .even

.odd:
move.b save1,$ffff8205.w
move.b save2,$ffff8207.w
move.b save3,$ffff8209.w
addq.w #1,counter
rte

.even:
add.l #screen_line_width,save
addq.w #1,counter
rte

save: ds.l 1
save1 equ save+1
save2 equ save+2
save3 equ save+3

Then you only need to load 'save' with the screen pointer in the vbl and then the hbl will do its thing.

Hope this helps
