I have listed a rare Mega Man handheld game on eBay. It is manufactured by a company named Sineca, and I think most of you have never seen another one.

Also, I will be listing some more rare goodies this week, probably even today or tomorrow. These goodies include a Taiwan-only copy of Zelda 64, a few Sachen games, 3 or 4 unlicensed Gameboy games, and more. Stay tuned and happy bidding!
