"Good clarification, but I still find it worth mentioning that the lower and upper nametables always show up in these two respective areas of PPU address space" - unless you're in 1-screen mirroring mode (which may or may not be supported - my implementation uses a 2-bit mirroring mode for V/H/S0/S1 and Maharaja seems to select S0, though it doesn't seem to do any scrolling). --Quietust 21:59, 27 February 2011 (UTC)
