Very cool! Sounds a lot like all the tricks you had to employ for the Atari 2600. If someone is interested in this, I can highly recommend the book "Racing The Beam". It's hard to imagine these days how complicated even the simplest things were back then.

15 years back I did some hobbyist programming for the GameBoy. Drawing a status bar there was comparatively easy. The hardware allowed you to set some registers to define a "window region", overlaying the main background map.
