16-Bit
From Bob and George: The Wiki
16-Bit refers to the sprite style from the SNES system. It has a much larger ability to have multiple colours on screen, relative to the former 8-Bit style, which, as a result, allows a much better depth and shading to the sprite.
The Main Site uses 16-Bit to show events occuring in the present (sometime after Mega Man 7 but before Mega Man 8).
