I noticed some bmp that were fonts/characters.  Like the input keyboard.  I guess you would have to redo the bmp file with larger fonts.

This might be easier than if they were actual fonts, though. We'll see.

I was kinda disappointed to see that really they are just throwing up bmp files to make up the screen.  No GUI rendering for the UI.   

I always wondered why BMP files.   Would it not be more efficient to use png files?  Smaller and less processing intensive?

The fonts are not in guiPicData.hex. They may be in guiResData.hex, but I doubt it. Most likely they were included in the main SparrowAPP.out encoded as 1bpp tables.

A few days ago, I looked for the bit pattern of the 'busy part' of a W or M (I forget) on the extra large font, but didn't find anything - too many false positives...

I'm sure they'll turn up as we identify more parts of the SparrowAPP.out and guiResData.hex data.

They're not using BMP files, they're using raw 16bpp data. I'm slapping a BMP header on them, because BMP supports that bitmap data type without a lot of extra hassle. PNG for example, does not really support 16bpp, only 8 or 24/32.
