Donkey Kong Country Cheats

This works in the stage, "Mine Cart Carnage". Hit the Star Barrel in the level, and then either die or pause and press "Select". Enter the stage again. When the Star Barrel explodes, IMMEDIATELY press Y and B simultaneously. You should now be jumping in the air, keep jumping by pressing Y and B in succession. You can use this glitch to jump all the way to the end of the stage.

NOTE: Do not backtrack to the beginning, as the glitch will stop functioning when you go back to the start.
