I was talking to my new friend ( ) Suppafly, and he told me that Duke Nukem was available for Genesis, but ONLY in Brazil. I looked for, THAT'S TRUE! It was released by TecToy, Sega's representant on Brazil. You won't find this in another place. I have 2 copies: 1 complete (box and manual and game) and 1 loose. It's VERY RARE. Anybody interested? Thanks!
