The Sega Genesis was one of the two great 16-bit systems of it's time, the other being the Super Nintendo. As Sega was not able
to obtain the trademark in the US, the unit was called Genesis there.
The Genesis had two major addons: a 32-bit extension called 32X and a
CD-ROM drive called Mega CD. Also, at some point a Sega Master
System converter was released that allowed it's games to be used on
the Genesis.
