Game Boy Advance (GBA)

Donkey Kong Plus [GBA – Cancelled]

Donkey Kong Plus is the name of an unreleased game demo developed by Nintendo as a demonstration at E3 2002. Nintendo had planned for the game to be an extension / sequel of the Donkey Kong Game Boy game. The player would have the ability to design and create levels on the GameCube, and play them on the Game Boy Advance using the GameCube cable. The user-created level could be tested out on the GameCube, then saved on a memory card.

Although the game was never released, it did inspire the gameplay of Nintendo’s Mario vs. Donkey Kong, for Game Boy Advance. A level editor was not officially available in this game, but it was included in the sequel, Mario vs. Donkey Kong 2: March of the Minis for the Nintendo DS. [info from Wikipedia]

An hidden level editor was found by Martboo48 in Mario vs. Donkey Kong, but to unlock it you’ll have to edit one single byte in the games memory code. It’s unknown why Nintendo hidden this editor from the final game, but it seems that Donkey Kong Plus and Mario vs. Donkey Kong could really be seen as the same project.

The Legend of Zelda II: The Adventure of Link have been introduced as a sequel of the masterpiece “The Legend of Zelda”, released in the NES on the year 1988 (1987 in Japan).
However, the only informations that have been discovered about this Tech Demo it was not playable, as the thousands of playable tech demos, this wasn’t one of the list. It’s probably just a testing graphics resource for the Game Boy Advance, because, it have a really nice detailed Hyrule Field Map (see images below).

As we can read on wikipedia, The Legend of Zelda: A Link to the Past & Four Swords was a collaborative development effort between Nintendo and Capcom, the process supervised by Minoru Narita, Yoichi Yamada, Takashi Tezuka and Yoshikazu Yamashita from Nintendo Entertainment Analysis and Development. Capcom had begun development of The Legend of Zelda: The Minish Cap in 2001, but temporarily suspended it to free up resources of the Four Swords multi-player component. The sprites and some areas were much different in the beta version, if you can make a complete list of all the differences in the screens and videos below, please let us know!

The Legend Of Zelda: The Minish Cap [GBA – Beta Hack / Unused Stuff]

Cendamos was able to find some interesting hidden stuff in the memory of this game. Items such as the Giant Hammer, Mega Crush, Enemy Set and Power Wrist were removed from the final game. Not much is known about these items, other than the Power Wrist was probably similar to the one in Wind Waker, giving the hero double the strength.

Also seen is what appears to be a baby Chuchu, or maybe a beta version of a regular Chuchu.

There was also a character sprite showing your stats on the menu that changed whenever your item or status changed. On the far right of the screen shot, you can see what it’d be like if you were being shocked.

Mario Kart: Super Circuit [GBA – Beta]

When it was first shown, Mario Kart for the Gameboy Advance looked a bit different than the final version. If you take a look a these beta images, the characters had bigger heads and smaller karts. Also it seems that the tracks had some differences in the details and in the course design, as we can see in the images and the video below.

Mattrizzle of The Cutting Room Floor discovered that there are a few unused tracks still in the final game’s data. Most of them appear to be Super Mario Kart’s battle courses, which means that they were probably at one point planned to be in the game along with the Super Mario Kart tracks. Unfortunately, the starting positions in each of the battle courses don’t exist, so the starting points default to position 0,0.
