A short track that never plays anywhere. Might have been an early title screen piece from before Konami obtained the rights for the TMNT theme song, or from a removed cutscene.
Appears in memory at 0x003436. Note that Stages 9, A, and B are levels that were cut from the game. Interestingly, the Elevator and Rooftop stage concepts were reused in Teenage Mutant Ninja Turtles III: The Manhattan Project.

All of the dialogue balloons in the game are stored as tiles, making it easy to find unused bits.
Unused boss (and Turtle) dialogue. The first balloon would come from Granitor the Stone Warrior, as he's the only boss that can scorch the Turtles. The second set could be from either Granitor or General Traag.
There are three unused pizza box sub-types that would give different power-ups. There's no code in the game to actually give the player these bonuses, though, so each pizza gives the energy bonus regardless of pizza box type.
To change the first object onscreen to an unused pizza box type, change the following memory addresses:
- 623C2 to 26
- 623C3 to 00 for Speedy, 01 for Whirly, and 03 for Zappy.
- 623C4 to 00
- 623C5 to 00
Zappy seems to be the most complete out of all of the power-ups. The player would be able to pick up a laser gun and fire lasers at enemies. It would have been interesting to have a projectile weapon in this game, but the possibility for that is gone now.
Change memory address 62045 to 01 to set Player 1's weapon to the laser gun. It seems that the coding for this weapon was never finished; it doesn't actually fire a projectile, and the laser gun emits no sound effects.
A sound clip for Speedy is in the game, but that seems to be the extent of that power-up's presence in the ROM. Whirly doesn't even get that much, though based on the name, it's plausible that the idea was reused in the sequel for the "bomb" pizza that causes your character to whirl around like a top, dealing massive damage.
Unused Foreground Graphics
A superabundance of sequestered scenery.
It's possible that the rusty metal tiles would have been used in their own stage, possibly the cut Elevator stage, and were shuffled into Stage 4 when that level was eliminated.
An old font and dialogue balloon are present early in the first Graphics ROM. Note that this is stored in a different place than Splinter's dialogue in Stage 4, which uses a different copy of the dialogue balloon and is not font-based.
Unfortunately, only half of the old font remains in the ROM. The other half was replaced by a small Teenage Mutant Ninja Turtles logo.
Unused Object Graphics
An exuberance of esoteric entities.
Some of these objects have been coded and have object IDs. Follow these instructions to alter the first on-screen object to the unused object:
- Set 623C2 to "XX", where "XX" is the given Object ID.
- Set 623C3, 623C4, and 623C5 to 00.
Object ID: 24
An alligator (It's not a crocodile; its teeth aren't visible when its mouth is closed) that would have appeared in the sewers. It slowly moves to the left, occasionally opening its mouth. It can't harm the Turtles in any way; like the mice that appear in the sewers, it was most likely designed to liven the place up a bit.
The palette is probably incorrect, but it's the closest matching palette found in the sewer area.
Hint: Not in the sewers.
|Flying (Used)||Rolling (Unused)|
No Object ID
The tires that the Foot Soldiers throw in this stage were supposed to either bounce along the ground or just roll. In the actual game, they simply fly through the air.
These graphics are used, but they're not visible during play.
Keeping with the standard franchise name change, the European arcade game's title is Teenage Mutant Hero Turtles. The title screen music wasn't changed, nor were the weapons that the Turtles use, making this change rather pointless.
The Japanese version has a subtitle (Super Turtle Ninja) not seen in other versions. The copyright date was also changed from 1989 to 1990 to reflect its later release in the region.
The Japanese versions fix an exploit in the scoring system. In all other versions of the game, the throwing weapons used by the Foot Soldiers give a point when destroyed. The player can rack up a lot of points by standing a short distance away from a Foot Soldier and destroying every projectile that comes their way. In the Japanese versions of the game, projectiles no longer give points.
