This game is a 2003 port of the original Donkey Kong Country for SNES. This version has increased brightness, at the cost of contrast and colour saturation, to make the game easier to see on an unlit LCD screen, some new features, including new minigames, hidden pictures, a Time Trial mode, and multiplayer games.
In order to achieve 101%, you need to play and beat every stage, find all bonus-rooms (only finding them is required, beating is not) and find all 52 cameras to fill the scrapbook. One camera requires you to collect the KONG-letters in every stage.
