I just got a copy of Jurassic Park for the Mega Drive.
Since I don't have any converter of any kind, I removed the top of my Genesis in order to insert the game properly.
Well, it boots, but I get that message which everyone knows of: "This game was developed only for use with Japanese Mega Drive consoles".

If I really want to play this that bad, do I need some kind of region by-pass code for the Game Genie? I know that there are devices out there that are better than the Game Genie, but it's all I can get right now.
