What a beautiful intro to assembly programming and reverse engineering. Very minor issues that bother me more than they should:<p>- Could it be that there is a whitespace missing after the &quot; ◐ &quot; or is the gap in the border intentional?<p>- X&#x2F;Z are used in the &#x27;program structure&#x27; example without introducing them beforehand (or mentioning &#x27;we will look at these later&#x27;).<p>- A real RE report would certainly have mentioned all visible part numbers and the type of I&#x2F;O controller. Although it is certainly not relevant to the game, it somehow bothers me that the author decided to omit this information. (hmm, maybe this was described in Section 3?)
