Believe me, they did weigh the alternatives. At the time it saved a significant amount of money and since they developed a software conversion routine and were anticipating that this routine, albeit CPU-hungry, would only be necessary once at the top of the frame for each sprite (hence not knowing about the HMOVE comb bug) it didn't seem like a big compromise. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html
