Unlicensed Mega Drive clones
From Sega Retro
The Sega Mega Drive was a commonly cloned console during the 1990s, especially in smaller markets. There are potentially hundreds of different models, though few have been documented on the internet. This page covers some of the consoles that we know exist, but don't know much else about.
Mega 16 Plus
This appears to be a regular Japanese Sega Mega Drive I shell with a different label.
Nippon Super Game II
A clone based off the Mega Drive II.
