Here are some beta / unused finds from Donkey Kong Country 2: Diddy’s Kong Quest! Robert Seddon linked us to another interesting topic in the DKC Atlas Forum, where Kiddy14 has found out about a beta video of DKC2 with lots of differences from the final version! In there we can see that there’s no fog in Web Woods, the Lava Lagoon has no lava and there are Klaptraps around there, the player can not swim in the water and there’s a storm in Mainbrace Mayhem and Krow’s Nest. For more infos check the original topic in the DKCA Forum! Also, they found some unused sprites for Dixie and Diddy Kong. There was also a character cut from the game. His name was Mr. X. It is speculated that he was supposed to be the boss of Gusty Gulch but never made it to the final game and was was replaced by another boss named Kreepy Krow.
Codes for unused levels and more can be found at The Cutting Room Floor!
