Just voted : interested, and might contribute.

The problem of a wiki is that anyone can alter (understand : deface) it.
A forum is indeed a good place for requesting changes.

If you want to know whether a validation is taking place, just watch the disk activity indicator (you may have to setup your emulation to windowed mode).

I had to boot up my A1200 just for this but the above code, checked on real 68030, does not set N, only V.

EDIT:
$30000/3 does not set Z, even if partial result is zero.
However, -1L/1 sets N.

ccr behaviour of div for v=1

Just seen something strange (for me) if a divide ends up in overflow.
This looks like :

move.l #$20000000,d0
divs.w #3,d0
Of course the result isn't written and we get v=1.
We also get z=0....
