Rather than figure it out I thought I'd ask first:

When getting a banner in any part of SS, it is recieves it as 96 bytes, each byte representing a pixel of the bitmap.

How can I determine what color is represented by each byte value? What I know of bitmaps is that if they are <= 8 bits they include a colortable. However obviously that isn't the case here.

So if you know how it works that'd be great.

isn't that just a 256 color bitmap then? 1 byte each?

ss graphics are 8bit bmp's that includes banners and everything.

Banners use the default SS palette, which is implied (not included) in the 96 bytes. If a given pixel has the value 12, then its color is palette entry 12. Open any of the default SS graphics files (or a banner file) in Photoshop and you can see the SS palette.

while the game does seem to convert a banner to ss palette regardless of color depth settings - I can still have a 32-bit bmp banner in my folder and use it

Right, the last 96 bytes tell you the 96 pixels, but they are flipped vertically... ... or w/e I had to take 12 bytes, and build it from the bottom up.. to have it display correctly

That's true for bitmaps in general, but not in the 96 bytes commonly sent bank and forth between the many clients/servers of SS.

I can only tell you how I got the banner to look proper after retreiving it from Merv.

Bitmaps with a positive height (in BMP header) are stored bottom up, and with negative height are top down.
