Adventure Island 2 (Gameboy) speedrun.

Here's a speedrun for Adventure Island 2 for the Gameboy. It's identical to Adventure Island 3 for the Nintendo Entertainment System. I don't actually have Adventure Island 3, so I used the Gameboy version. However, I do have Adventure Island 2 for the NES, but it doesn't actually belong to me. Keep in mind, it's not very good. It's just a basic start for those who want to a speedrun. Let me address the differences between the two games. The first Adventure Island 3 boss stays put in one spot while in the Gameboy version, he moves around. The third boss in Adventure Island 3 has a slightly different shooting style then in the Gameboy version. The fourth boss (the shark) in Adventure Island 3 moves in a cyclic pattern left and right while he can also move up and down in the Gameboy version. The fifth boss (the skeleton head) in Adventure Island 3 is set up completely different then in the Gameboy version. The seventh boss (the butterfly) acts the same, except the platforms are in different spots in each game, and the room that the boss in is slightly bigger in the Gameboy version. The eighth boss (the UFO) moves left and right in Adventure Island 3 while in the Gamyboy, it's also programmed to follow you and have a basic idea of where you are (it tries not to let you shoot it). The ninth boss (the alien) in Adventure Island 3 is completely different then in the Gameboy version. The music in Adventure Island 3 is way better then on the Gameboy. Adventure Island 3 plays faster then the Gameboy version. Adventure Island 3 has a bigger screen, so there's more room to fight bosses then in the Gameboy version. The secret rooms where you go to proceed to different paths are way bigger in the Gameboy version, then in the NES version (Adventure Island 3). The actual levels themselves are exactly the same, as far as I know. I don't actually own Adventure Island 3, so I have not checked this out too much. It looks like the Gameboy version is superior, but not necessarily. Of source the Gameboy had its problems. Enjoy.
