Not having tested it, I guess using movep for 8pix speed 4plane scroller should be okish. It would need the font to be scrambled though. It you have a big font (64 width) all dataregs can be used to fetch data and then do 8 movem.l, eg
movem.l (a0)+,d0-d7
movep.l d0,(a1)
movep.l d1,1(a1)
movep.l d2,8(a1)
movep.l d3,9(a1)
movep.l d4,16(a1)
movep.l d5,18(a1)
movep.l d6,24(a1)
movep.l d7,25(a1)
My guess (as I said, not tested) it could be a bit quicker than 64 move.b x(an),x(an). If I've thought all wrong I blame the bad weather!

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.
