I've found an example of prefetch mode and auto modified code that explain my precedent message :
moveq #0,D0
lea wcode,A0
move.l #$4E714E71,(A0) ; NOP opcodes
wcode:
addq #1,D0 ; written here
addq #1,D0 ; and here
What is the result in D0, zero, one or two?
Also if this isn't the answear of the Apex Demo problem, I was just thinking if this is correctly taken into account by emulators (Steem, Hatari, Aranym end Saint).
Regards,
Laurent
PS : Sorry for the double posting of my precedent message.

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.
