That is the idea..  New "softswitches" for **incompatible** video
modes.
Not a very useful thing (zero software available to take advantage of
it)
but it would be a fun project.

in your example above, 1 pixel = 256 colors (eight bits, 1 byte)

I'm going to get around to this project myself, eventually.  I'd like
to hear of other resolutions / color schemes.
