Does anyone have any 'Minecraft' related game codes out there? If so, I would like to try it.

no you can get banned from smilebasic for copyright

I don't have the key, but I believe someone is making a 2D Minecraft clone you can play. It's unlikely you would get banned for a clone game, since Nintendo sells a few themselves through third party compnies on the e-shop.

yes it's called petit world but i don't have the key sorry.Look in smilebasic source it should be there.
