I just picked up at Goodwill a Famicom to Nes Converter made by Honeybee. And it had a Nintendo made in japan 20 in 1 cart with it. It works good but some games are different that what it says on the menu. Also for some strange reason 1 in every 4 or 5 times you start it , it starts as Double Dribble and not as a 20 in 1 cart. Well anyway, is it worth anything?
