This may seem like an odd thing to ask, but what NES games have diagonal scrolling (without vertical or horizontal wrapping)? The only one I can think of right away is Ninja Gaiden III. Any others?
Technical crap begins here:
The reason I ask is that the stuff I've read about the NES PPU suggests that it's not well-suited to diagonal scrolling without having extra RAM on the cartridge - the circuitry supports a big enough BG space for it and has the appropriate features, but with the RAM inside the PPU, there is only enough room to define two BG tables; four would be needed to provide straightforward, smooth diagonal scrolling. I can think of a couple possible tricks to get diagonal scrolling without the extra RAM, but I'd like to know if there are any games that manage to actually do it.
