So did I, in fact I just bought it yesterday. Sadly, no there is no other legal way of playing this game.
I never played the snes version so I couldn't tell you but honestly it's not worth buying an N64 just for this game. An N64 is worth buying for a lot of games, some of which I still play.
When I said legal I wasn't encouraging anything. I myself can't stand playing my N64 games any other way than on the system itself.
