The best Ghostbusters game is Ghostbusters 2 for gameboy. I've tried playing all of the other ones and found them to be no fun. GB 2 for Gameboy was great because it was like playing Zelda except with the Ghostbusters. You fight the Scoleri Bros and a few other ghosts from the movie. I also loved using the pick axe to break through walls. Sorry for being so stiff.
It really is the best freaking game. Go find the rom. It took me awhile to find it, but it was worth the time. If anyone wants to upload it I can send it to them. I don't know how to upload stuff.
It's the best one I've played. Better than New Ghostbusters 2 on the NES I think. I still have it somewhere. There was also a Real Ghostbusters game for the Gameboy which I never got the chance to play. I heard it wasn't that good though.
