Calculating which frame to use >is pretty simple, as long as all the frames are stored in ROM. I meant you'll have to design 100 frames of animation and then turn them into ROM data by hand. That would be a lot of work. Maybe I should write a PCX to DATA converter, that would do this automatically. >right (approx 10 moves for each character, each with 10 frames.)

To get the detail >level of MK1 on the 2600 (in monochrome, though), you'd need 300*94 = >28200 bytes per character. It'd be doable with one character, or two You are right, but 50 bytes for each collumn would cross page boundaries, wich would affect timing. I would say we go with 42 bytes, since 42*6=252, which would fit nicely into one page. Or since some of the collumns would look the same in different animation frames, maybe we should store the data column wise and use a table, that tells us which collumn to use for which animation frame. That might save some space.
