Can you play nes and snes games on the wii with a gameboy controller? - nes controller bluetoothbuy

I know it's you can buy a converter to connect an NES or SNES controller to connect to the controller port on the Game Boy Wii, but I really do not want to buy.

When I download one of the old games on the Wii, I can play Game Boy with a controller or I buy the converter?
