Now that the dual port memory is working, we need to start doing heavy work on the sprite drawing. As a test, implement a design which:
VRAM with a new image every so often.
Remember not to change the VRAM location, the VRAM must always be at address 0h. Actually have a module that copies data per pixel into the VRAM. This seems silly for a slide show, but it will be required once we want to actually draw sprites.
