Mario vs. Donkey Kong

Mario vs. Donkey Kong is a platform/puzzle game developed and released by Nintendo in 2004 for the Nintendo Game Boy Advance. The game features e-Reader support, but only in the Japanese and North American releases, however only 6 of the planned 12 cards were released in Japan. Levels for the undistributed cards are accessible with hacks in both the Japanese and NA version, but all the American levels seems to be beta versions of the Japanese ones.
