The Sega Genesis had some of the best movie-based games for its time. The ones that stand out for me were the three Disney games I have owned for this system. Aladdin, being one of them, was indeed one of my favorite games for the console, and I certainly had some fond memories with it, too. I can still remember some of the level tunes and the secret code for skipping a stage (pause, then press A,B,B,A,A,B,B,A).
The other two, which I've registered under "Something I forgot!", were The Lion King and The Jungle Book. I'd love to have sound experiments with The Lion King the most out of all of the games. There was a part or two that was difficult to overcome until a bit of figuring was done, and the game was required to be beaten with a six-button controller (Scar needed to be thrown off the edge by pressing either the X,Y, or Z buttons). This game, too, had some fond memories to go with it. As for the Jungle Book, I seem to remember more about this game than the other two. I sure did love the music that was used for the river stage where the player had to search for Baloo, and for the night jungle stage, as well, which sounded like a death approaching (I believe it was used for the game over screen as well).
Now that my Sega Genesis is in a mysterious place, these games remain as only fond and distant memories to me
