How can you link a Gameboy DS to the Nintendo Gamcube for Gamecube games that can utilize the Gameboy in them?

Answer 1

you cannot. there is no connectivity.

i am aware that you are talking about the gameboy advance games that are used *through* the DS, but in order to make those games communicate with the gamecube, you must use a gameboy advance.

there is no other way. there are no pieces of equipment that will allow a DS communicate with a gamecube
