Bet you can't do it in a week :) I have the feeling you're right. I managed to get some appropriately-sized images, split them into color channels, dither the channels down to monochrome (yes, ImageMagick *is* great!), and then run each of those through Banker. Unfortunately, I'm, at worst, plagued by illegal instructions, and at best stuck with an image that bears no obvious relation to what I wanted (depending on how I manipulate the offsets in the frame table). The Chronocolor source claims that "Each line is a single sprite, 128 butes deep"... When I run banker over *my* images, I get something like: ; TEXT_RED00.asm ; Created by Banker v0.01 ; Sprite set. Each line is a single sprite, 16 bytes deep, defined bottom-up ; This bank contains 1 frames, consisting of 24 sprites. This seems like a lot of sprites, and it's worrying that they're 16 bytes deep. I think perhaps I don't really understand what banker is doing to produce the sprite table from the image you feed it. Would you make the banker source public?
