aaaaargh, i give up. probably i should spent more time with hardcoding than with dsp since i'm dumb dumb dumb!!
is there any reason why this shouldn't work:
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:
move.b $ffff8205.w,save1
move.b $ffff8207.w,save2
move.b $ffff8209.w,save3
addq.w #1,counter
rte
(written from memory but you see the idea)
this should do software double lining, i'm trying to do this in xxx x 240 mode, i.e. with hw doubling.
it seems semi working but the screen is totally screwed up and i've tried countless of experiments with no results. when i replace move's with simple not.l $ffff9800.w i get stable rasters, black-white-black-white so even is really called in even line and odd in odd line.
probably there's something i miss with video counter?
thanks for any help to desperate falcon coder ;)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
