Battletoads (Game Boy Advance)

Unreleased The GBA Battletoads is an unreleased game whose prototype was released by RareWareCentral on November 19, 2011. The prototype is very primitive and doesn't even have a proper title screen.

Levels
There are eight levels in this build. While a few are more polished than others, none are truly finished: they can be glitchy to play, and none of them have exits. They can only be entered by using the debug features. In-game, the levels don't have names, but searching through the prototype with a hex editor starting at shows a basic list of level names that seem to match with the levels on the ROM.

Ragnarok 0


Probably the most complete stage that could have made it into the final product had the game been released. The level has a few different enemies, the most abundant of which resemble Psycho Pigs from the original NES game. There are also a few enemies that resemble Walkers. There is a glitch halfway though the stage where your character has limited movement and there are constant sounds of a Dragon being heard.

Ice Cavern

The second most complete stage is a replica of the fourth level of the original NES game. There are no enemies, you can't get hurt and several of the original level's features are missing, such as the moving platforms and snowball barriers. Due to a glitch, it is very easy to jump through walls and when you fall very fast the graphics mess up until you land.

Test 0


A replica of the first stage of the NES game. This stage has not only Psycho Pigs and Walkers, but two invincible Dragons: while the first tries to attack you, the second flies where the first boss of the NES game was. This replica actually has graphics from the NES game in it, including sprites of Rash, Psycho Pigs, a Walker leg, and some detail of the old HUD. Portions of this level might have been used as inspiration to create Trial 0 and ultimately Ragnarok 0. Evidence of this can be seen around the waterfall area, as the layouts from all three levels look similar there.

Trial 0


Seems to be an early Ragnarok 0, with a near-identical layout. Minor differences abound, such as Ragnarok 0 being slightly bigger than this map, a few layout differences, and the fact that Trial 0 uses placeholder graphics to show the layout. The only enemy is a Dragon at the very beginning of the stage.

Test2D 0
A very short level that doesn't have much graphical detail. There are two Psycho Pigs that stand on top of a platform and throw pig heads (probably placeholder graphics for what would have been the projectiles). Curiously, the background image comes from the ship hold levels in Donkey Kong Country 2, such as Lockjaw's Locker.

Trial 1
Even shorter than Test2D 0 and using placeholder graphics, this consists of a long shaft with four platforms (two each at the bottom and top), although the latter can only be reached through glitching or debugging.

Trial 2


Uses the same graphics as Trial 1. This stage has similar physics to Ice Cavern, the key feature being that you can slide down slopes. While smaller than Ice Cavern, Trial 2's layout almost matches perfectly with the beginning section of Ice Cavern. The similarities can be seen by comparing the image of Trial 2 to the first 40 seconds of the Ice Cavern video. It is clear that Trial 1 and Trial 2 are early versions of Ice Cavern.

Test Mode 7


An interesting level that uses graphics from another unreleased Rare game, Diddy Kong Pilot, and the level looks like one of the racing levels from that game. The controls are different than the other levels, and it is clear that this was intended to be a flying level but it is far from complete. Left and Right move the player left or right while Up and Down move forward or backward. Pressing A or B will raise or lower the player respectively.

Debugging Features
This prototype has some basic debugging features.

Free Movement
Enabled by holding Select and using the D-Pad. This can be used to move the player around to the desired position. Pressing A or B will raise or lower the player respectively. The viewing window will also scroll in the direction the D-Pad is pressed, although it scrolls faster than the player and can result in the player going offscreen. The viewing window will recenter on the player when Select is released.

Level Select
By holding Select and pressing L or R, you can enter any level. R and L move down and up the list respectively, and the list loops. This is the only way to get from level to level.

Error Messages
Starting at is a bunch of text relating to audio errors, which are very similar to those of Donkey Kong Country.
