Never heard of Ganja Farmer so I did a quick Google search. Apparently it's a PC game that you're trying to get to work with a Turbo Grafix16/PC Engine emulator? No offense but it sounds like you've been visiting the real ganja farmer. lol. There may be a chance of you playing it on your wii though because it appears to be a DOS game so you can probably use DOSBox to run it.
