Karri informed me that I can use the full range (16-bit) for the virtual display where you place the sprites in. However, glancing through the lynx docs I see an example that mentions that only the first 9 bits (512) are available for use. Can someone clarify this suzy related question for me?

I suppose He meant you can use any ram address (16bit) for the display buffer.

You'd think so, but he said:

"Your playfield is actually the full 16 bit pixel range (65535 by 65535 pixels). This means that you can write your sprite anywhere and let your 160x102 viewport smoothly scroll over the playfield.
"
