Well, I'm trying the worst cases so ... -1 and 1
I know it's pretty obvious that the 68000 add.l adds the full 32 bits
and that's why I'm asking, HOW this UUuuVVvv tricks can actually work ?!
because for me this trick cannot work.
unless you take specific measure of special case (like negative number)
but you know, it's bean 7 years that I'm trying to make a 3D engine, I'm so bad at math I can barely have something working after 7 years...

Don't have a code or forgot it? Fix it here.
