E3 2002
At the start of E3 2002, Nintendo revealed a game titled Donkey Kong Plus - stylised as Donkey Kong + on Nintendo's official website[1]. According to the game's fact sheet [2], the game would've been a remake of Donkey Kong '94, featuring over 100 levels, new moves for Mario, and new to this remake; a level editor with GameCube Link Cable functionality, with players being able to save levels to the Memory Card, transfer them to the Game Boy Advance and trade them with friends. No other info was shared, with the game being slated for a Q1 2003 release date as a Game Boy Advance game.
Two levels based on those from Donkey Kong '94 are known to have been playable at the E3 showfloor, with one monitor showing the game, and another demonstrating the Link Cable showing levels on the Game Boy Advance. The level editor was very simple. Pressing Up/Down on the C-Stick would've allowed the player to toggle between building materials, characters, special items and three required items, those being Mario, a key and a door to the exit. The A button allowed you to place the item, B to remove an item and Z to toggle a grid on the screen. Pressing Start/Pause would allow you to play your edited level either on the GameCube or the Game Boy Advance. During gameplay, the player gets to see what level they're in, the time represented by a counter and bar on the side, a score, lives and three collectibles that need to be collected. After completing the level, a screen would appear reading "GREAT! YOU WIN!" using updated artwork of Donkey Kong from Donkey Kong '94's title screen. A few graphics based on this early design for Mario are still present in the final game.
After E3, the game wasn't heard from again. Near the beginning of 2003, Nintendo updated their official website reading that no release date has been announced. Between E3 2002 and E3 2003, the game would be reworked into Mario vs. Donkey Kong as a standalone title for the Game Boy Advance. The only known screenshots of the game originate from IGN[3], with the only known footage being a 15 second snippit from Planet GameCube's E3 2002 "Shine Get" DVD[4].
E3 2003
Mario vs. Donkey Kong, then known as Mario and Donkey Kong, was first revealed when Nintendo sent out press kits to gaming news organisations. Nintendo didn't share any other details however[6], other than twelve screenshots.
General Differences
All that stuff goes here...
E3 2003 Showfloor
Reported by IGN[7] and David Dayton[8], the game was playable from a single Game Boy Advance on the E3 showfloor. No pictures or videos seem to exist.
According to IGN, the game was already close to being finished, aside from the lack of an interface before entering a level. Many of the things described in the article show up in the final game, though the plot synopsis is different.
"The game features a storyline where Mario opens up a toy factory manufacturing Mini Mario wind-up dolls. Donkey Kong feels left out since Mario never made a DK doll, so the monkey has infiltrated the factory and stolen many of the toys before hopping off deeper into the factory. It's up to Mario to traverse the hazards of his factory to grab the lost toys and head to the next part of the building."
In the final game, Donkey Kong is upset that all the Mini Mario's are sold out, and ends up robbing the Mario Toy Factory - which was already opened without an introduction - before Mario takes notice and goes after him. The idea for Donkey Kong to travel deeper into the factory was reused for World+.
E3 2004
 | To do: Check screenshots. E3 2004 b-roll appears to slightly predate the kiosk demo in terms of scores you get from collecting presents. |
Unused Levels

Unused Objects / Graphics
| To do:
|
All offsets apply to the US retail game.
Placeholder DK Mech Hand
Offset: 0x1CFAC0
Format: 8bpp
A crude placeholder graphic of DK's mech hand, found among graphics of the final boss. Unfortunately, no palette seems to exist anymore.
Placeholder Cage
Offset: 0x12E3A4
Format: 4bpp
Placeholder graphics for a cage, found among other general graphics.
Early Mario Graphics
These few graphics are scattered across the game, taking on a more standard sprite approach for the game's art style instead of pre-rendered graphics. The design for Mario seen here closely resembles that from what was seen in Donkey Kong Plus.
Offset: 0x457E40
Format: 8bpp
Mario stuck in a ball, found among other graphics for Mini Mario.
Offset: 0x5A10B0
Format: 4bpp
Two frames of Mario possibly grabbing something.
Offset: 0x5B18AC
Format: 4bpp
A single frame of Mario performing a backflip. When compared to the backflip animation from Donkey Kong (Game Boy), Mario's moves closely match that of the 6th backflip graphic.
Mario & Donkey Kong Running
Offset: 0x2F9184
Format: 4bpp
A full nine frame animation of Donkey Kong running away. Not only is this animation considerably smaller than any other animation with him, but he's also running away without his sack. No palette seems to exist unfortunately.
Offset: 0x2F9E54
Format: 4bpp
A similar twelve frame animation for Mario exists as well, also in a smaller format and lacking a proper palette.
Pause Menu Text
A few graphics from an earlier pause menu are leftover. The pause menu is in the same style, but the text is different.
Offset: 0x2EDE24 & 0x2EF194
Format: 4bpp
A restart option, which was retitled to "RETRY". This graphic is split up into two parts.
Offset: 0x2EDCF8 & 0x2EEF44
Format: 4bpp
A quit option, which was retitled to "EXIT LEVEL".
Offset: 0x2ED8C8 & 0x2EE704
Format: 4bpp
The most interesting however, is an edit option, leftover from the scrapped level editor.
Glass Ball Slot
Offset: 0x514094
Format: 4bpp
Much like keys, glass balls containing Mini Mario's were also intended to have a visible slot when they were picked up. Although the palette is no longer present, screenshots from E3 2003 do show what the graphic looked like in-game.
Early Boss Health Bar
| To do: MvsDK graphic exists here too - duplicate? |
Offset: 0x2E911C
Format: 8bpp
An early health bar for the boss fights found among Mini Mario and barrel warnings, using a simple bar rather than displaying Mini Mario and Donkey Kong heads.
Unused Functionality
"Main" Level Select Button
| To do: basically the menu button is selectable and functions when pressing A, but some palettes may be fucked |
Early Opening Cutscene
A bunch of assets and code for an alternate, early opening cutscene when starting a new save file exist in the game's data. This opening cutscene is more dummied down, featuring only a specific palette for each slide and dialog for all characters. Some parts of this cutscene were overwritten, including a couple of sound effects that were replaced with those from the opening cutscene, and a proper palette for the text, making the text hard to read.
To view this cutscene, change the first four values at offset 0x2D4C4 to 0CE9B208 in the game's US retail build. The cutscene will play when starting a new save file.
The dialog is as follows:
| Character | Text |
|---|---|
| DK | GRRRROOOOOOWLLLL!! |
| Gimmie all your toys!! | |
| Toad | WAAAAAAAAAH! |
| Mario | Whats going on? |
| Toad | Donkey Kong stole all the mini marios!! |
| Mario | I will get them back!! Here we go!! |
