The ROZ layer stuff is looking really good.

Does the ROZ layer use the same flags as the normal tilemap layers? If so, are they disabling the wrap scroll enable flag when the images are rotated in?

I don't remember anything about the mode 7 settings on the SNES; but could the A'Can have based their ROZ layer on the SNES'? Especially since the Gameboy Advance was pretty much considered a handheld SNES (with a better CPU).
