I used this one:
lea xtab,a0
lea ytab,a1
;---
; D0...x
; D1...y
; A6...screen
add.w d0,d0
add.w d0,d0
move.l (a0,d0.w),d0 ; pixel_data | offset
add.w d1,d1
add.w (a1,d1.w),d0 ; + y offset
move d0,d1 ; offset
swap d0 ; pixel_data
or.w d0,(a6,d1.w) ; set pixel
I guess it's easy to see how xtab & ytab have to look like..
Regards,
Defjam

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.
