Power on 160x128 .bmp logo not filling the screen

Hello! I successfully uploaded a custom 160x128 .bmp image to the DB-25. Perfect!

However, when I try the same with the GD-88 the image is only about 30% on screen.
At least it's displaying, but it would be nice if it covered the entire screen like the DB-25 does. Thoughts? Happy New year!

This is a firmware / display "issue"

The GD-88 I believe uses a different screen or different resolution / scaling so the boot logo doesn't display the same.

Hence why I added the ability to change the background colour. Since it just takes the colour from the top left pixel and fills the background.. Which may not always look great, depending on what the pixel colour is.. So changing it to a custom colour.. or even just black.. helps make things look a little better. :)
