Hi,
You should replace clr.b opcode by move.b with a empty register, 4 cycles faster!
Btw the CPU only option with the move.l trick is never win. Move.l solution is 8 nops;
move.l (a0)+,d0 3nops
clr.b 0(a1,d0.w) 5nops
you can improve this using move.b instead of CLR
move.l (a0)+,d0 3nops
move.b d1,0(a1,d0.w) 4nops (d1=0)
But better use two patches. When you first patch the or.b, you can patch the clear instruction with a simple:
move.w dn,x(an) ; 3nops, patch the clr.b x(an)
move.b d1,n(an) ; 3nops (d1=0)

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.
