Sprite Multiplexer? Never heard of such a device... Well, anyway, your fakes don't look to be QUITE valid... at least some things would have to flicker in the real thing... Let's take this from top to bottom... The score display would be doable. Nothing special here. The playfield can't have another background color than the border is, unless it would be 160 pixels wide, which it isn't in your shot (only 112 pixels). The question signs, if you display multiple on one line, would have to flicker. A solution to that would be to make the walls 8 pixels wide instead of 4, so you'd end up with a spacing of a multiple of 16 pixels, which could enable you to design the mazes so the question marks can be displayed as multiple copies of one player. Still the spacing would have to be 2 or 4 squares between them, not 3 as shown here for the upper and lower question marks, so basically, if done this way, the mazes would have to be re-designed. The red eyes of the creatures also look unrealistic. If moving left and right, they could be done with a missile of the red players (but what about multiplexing then?), but when moving up and down, there would have to be two missiles next to each other, which is quite impossible, other than flickering, which doesn't look very good. Still, the kidturtle being on the big one could be displayed with the ball, but the question here is if there's enough cycles in the kernal to do it. But since everything else seems to be rather simple to do, there might be enough... Finally, the bottom display... it seems to be two six-chars next to each other, which is also impossible, unless you let them flicker. The other, non-flickering variant would be to abbreviate the text displayed there and squeeze the two-digit numbers into 8 pixels, as it's done with the letters now. Then you could do two sets of 16 pixel wide displays, which in this case would show something like that: P-00 H-06 F-02 B-22 I don't know what looks better, this one, non-flickering, or the two flickering six-chars... And please, include the music from the original! I loved those tunes already back then and even did a song out of them (where these melodies were mingled with tunes out of Amidar, and with Simon & Garfunkel's "Mrs. Robinson"). With love from Austria (and much music to write) Kurt Woloch P.S. Are there any screenshots of the Ebivision version of Pac-Man somewhere? - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
