>I've considered that flashing might be used in another Pac-Man >port. One frame would render the maze, and one would render the >dots. I could have a sample 4-colour pacman playfield up in a couple hours, if anyone is really interested in what it'd look like. Gotta be more than a couple of people express interest, though, to make me do it :) Strangely, I have already written several pacmans - officially - including Super Pacman and Pacman Junior on the C64 (both released) - way back when - and my own Atari 800 pacman clone even earlier than that :) Hate to see it called "that flashing", though ... as it seems to be my baby, I claim naming rights. I christen it uh... mmmh... the 4 colour playfield. You can tell I'm a programmer, can't you? > The maze would be blue on black background (like it's SUPPOSED >to be) while the dots would be greyish or yellow. This way we >could create a more arcade-accurate maze and a less strenuous kernel >per-frame. An additional advantage of this is that any other >objects that are flashing on alternate frames will appear solid, >in comparison. Other details, though, are unresolved... including >who will code this thing, and if me, when will I have the time? Well, maybe me after I've finished project #1 :) But I'm afraid I'd be sued if I really tried to release the thing. We'll have to rename it munchman or something ;) I expect this would be quite a quick project. >A flashing routine with a frequency of 1/2, which I imagine your concept >to be Yes, I am sticking with a 1:1 ratio for each of the two playfields - that is, they display on alternate TV frames, giving 30Hz on NTSC, and 25Hz on PAL.
