Game Boy Advance (GBA)

Mario vs. Donkey Kong [GBA – Beta / Unused]

Mario vs. Donkey Kong is a Game Boy Advance spiritual sequel to the first Donkey Kong game for Game Boy, developed by NTS in 2004. The game concept revolves around a combination of platform and puzzle elements, challenging Mario to find keys, reach a locked door, and rescue mini-Marios. [Info from Wikipedia]

Upaluppa and Kiiro found many unused stuff and beta levels still hidden in the final game’s code, as a a prototype version of the MvsDK e-card levels, Mini Marios trapped inside crystal balls as keys, some unused coins / stars and a working level editor. It’s possible that the Level Editor evolved from the unreleased Donkey Kong Plus.

Also, an unused Bomb-Ombs behavior. As wrote by upaluppa:

they start running around scared, just like Shy-Guys do, when Mario is equipped with the hammer! You’ll never see them running normally, because none of the levels with Bob-Ombs includes hammers…

Thanks to Hiccup for the contributions!

Broken Circle [GBA – Cancelled]

Broken Circle is an unreleased rpg created by 7 Raven Studios. The game, which story was based on Nordic mythology, had a troubled development: publishers weren’t interested because it was too risky to cover the release costs for an unknown title that needed a big and expensive 256mbits cartridge.

By the time that the programmers managed to shrink Broken Circle to 64mbits, the console was at the end of its life and the only publisher interested in the game was not officially authorized by Nintendo.

In 2009, 7Raven Studios decided to release a rom of the game on its website, but now the download link is broken. The rom can be easily found with a google search, though.

Props to 7 Raven Studios for sharing Broken Circle with the community! If you are a collector, you can buy an official cart of Broken Cirlce for GBA thanks to Piko Interactive.

Monster Hunter [GBA – Cancelled]

Monster Hunter (not related with Capcom’s Monster Hunter) was an action game that was in development by Contraband Entertainment for the GameBoy Advance. As we can read from the original press-release:

In Monster Hunter, you are the one-eyed hero who travels to the five towers of evil. Your mission as the Monster Hunter is to destroy the various creatures wandering the maze of hallways and to recover the fable treasures contained within the ancient structures.

Seems a simple task, but it’s not. There are weapons scattered throughout the levels for the player to use against the monsters, but only one specific weapon will slay a certain type of creature. Some of the weapons will temporarily stun a monster, but that same weapon can power-up another type of creature.

For some reasons it seems that the game was never released, even if it could have been finished.

Mario Golf: Advance Tour [GBA – Beta / Unused Rooms]

Mario Golf: Advance Tour is an RPG-styled sport game developed by Camelot Software Planning and published by Nintendo for the Game Boy Advance in 2004. The game is the sequel to the Game Boy Color version of Mario Golf. [Info from Wikipedia]

Robert Seddon has recorded an interesting video about some of the debug rooms and unused areas that can be found in the Mario Golf: Advance Tour game code thanks to the Atrius’s Golden Sun: The Lost Age editor (as both games use the same engine). We can even notice some GBC-alike sprites, probably used as placeholders. The beta” foyer had some different details as you can notice from this comparison:
