I entered some Game Shark codes for it last night, and when I start the game, I just get a black screen with weird noises.
I tried turning some of the codes off, and I STILL got the same thing! Does anyone know any codes THAT WORK?

GameShark, or Codebreaker? I have my own Gameshark and Codebreaker, alothough I never did use my Gameshark on my Megaman and Bass. I did use my Codebreaker, and what you said happened to me, too. Thing is, some hackers really suck, so this happens. So I guess for now, there is no code for this game. Yes, I know, it sucks, but it\'s life. So, you have to do it on your own... I just wish it worked for me, because I can\'t beat the game...
