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?
