I've been trying to think of a simple way to add hardware sprite support to VGA breadboard projects, and will be developing this idea further soon, at least as a starting point!
Conceptually, this design should be easy to add to pretty much any VGA breadboard project, and it should be possible to support nice large sprites with maybe three colours plus transparency, but of course it's mostly aimed at my Simple 6502 VGA project at the moment.
Let me know what you think!
