I regret getting this master gear convertor think for the Game gear. I never bought a single master system game for it. lol

 

Converter for Game Gear?  I know of the Sega Nomad which was a standalone system that played Genesis games.

And the Power Base Converter (or Mega Adaptor in Japan, Master System Converter for Europe) for the Genesis that allowed you to play Master System games.

But I never heard of a Sega Master system to Game Gear converter.  I assume you meant the converter for the Genesis.
