Question: can 3ds play gbc games?
Answer: Also yes, you can buy Gameboy, Gameboy Color, Game Gear, and NES (and SNES on N3DS) games on 3DS through the eShop under the Virtual Console section. You can not play actual carts of these old games on a 3DS and you would need a Gameboy Advance (or Gameboy Advance SP) to play the physical cartridges.
