Mike Tyson Boxing NTSC?

[Frogg]

Was wondering if anybody knows in Mike Tyson Boxing the NTSC/UC united states version has a protection on it. I went to megagames.com and they said it was protected so I got the protection fix/pal & ntsc patch well everything went well with that. I went to go play it and after the intro I press x then to go on and play the game well I get nothing but a black screen and the game never loads. So can someone please help me out with this game. Thank You!
