To do: Investigate the Nintendo debugging tape. If these bugs don't appear in the final game, document it in a prerelease page. See if there's any other beta stuff here (graphics, objects, etc). (timestamp 1), (timestamp 2), (timestamp 3), (timestamp 4).

In Blast Corps, your goal is simple: destroy buildings everything using a variety of unique demolition vehicles to clear a path for a truck carrying a pair of defective nuclear missiles.

Unused Level Features The mysterious toilet...

Unused Objects There are even more fences?

Unused Textures The player isn't always that happy...

Unused Code

Destroy Containers Level

There exists data for a level type where you have to destroy containers like the ones from Oyster Harbor.

HUD Icons

Icon ID 0xFC is a duplicate of the Destroy Spheres icon.

Big icons for Cyclone Suit, damage counter and timer exist. They use the same graphic as the normal ones, but they are resized. The unused icons use the IDs 0x27, 0xED and 0xEF respectively. The big Cyclone Suit icon was meant to be used in the Highscore list, but no bonus level uses Cyclone Suit.

The crane, train, boat and the unused vehicle have icon IDs, but they all display the same glitched graphics. Their IDs are 0x06, 0x07, 0x0B, 0x0C for the normal icons and 0x1D, 0x1E, 0x22, 0x23 for the bigger ones.

Placeholder Data

An unused vehicle (0x0C) exists. Trying to load it crashes the game as there is no code for it. This slot was most likely used by the removed rescue chopper vehicle.

There is an unused event with ID 0x1F located between the final intro segment (0x1E) and the main levels complete message (0x20). The game will freeze, because there's no text assigned to it.

In the savegame file there are some unused bytes for activated communication points for levels that don't even have one including Diamond Sands, Morgan Hall, Mars and Gibbon's Gate.

Unused TNT Blocks

The fourth parameter controls the type of a TNT block. 0x01 uses a different texture and 0x02 is an invisible TNT block. In the final game said parameter is always set to 0x00.

Other

English	German
REACTOR MELTDOWN!	KERNSCHMELZE

Meant to appear after the WARNING! message, but the final game uses COLLISION IMMINENT! instead.

INSERT CONTROLLER PAK OR PRESS START FOR A PASSWORD

Text related to the Controller Pak.

***** YOU CAN STOP NOW!! *****

This text would have been displayed after collecting all 57 platinum medals, but was scrapped for unknown reasons.

GOING FOR NEW:%x
OLD:%x

Text with unknown purpose.

Unused Music

Moon - Warning! (0x24)

Action themes don't play in bonus levels, which means that there once was a level that used the moon theme along with this unused song. This can be heard in the inaccessible level CMO Intro.

Moon - Ending Jingle #2 (0x3F)

Each carrier level uses two different ending jingles. While the first one is used by default, the second jingle only plays when the player enters the Blast Corps semi at the end of a level. Since the Moon theme is only used in bonus levels, the second ending jingle can not be heard during normal gameplay. Interestingly, it doesn't play in the inaccessible level CMO Intro.

Unused Sounds

Alternate Warning Sound

Warning!
Many unused copies of the "Warning!" sound are present in the second sound bank.

Spike Dialogue (Sound No. 61)

What's the matter with you?
This sound is found between "Give me a break!" and "You keep this up!". Where this could have been used is unknown.

Unused Instruments

There are a few unused instruments, but most of them are just copies from other instruments.

ID	General Midi	File
0x1E	Distortion Guitar
0x1F	Guitar Harmonics
0x24	Slap Bass 1
0x2B	Contrabass
0x2C	Tremolo Strings
0x3E	Synth Brass 1
0x46	Bassoon
0x47	Clarinet
0x48	Piccolo
0x49	Flute

Version Differences

To do: Apparently the Rare Replay version replaced one of the music tracks, since it was also present in Donkey Kong Land and might have had some licensing issues. Does the Switch version do this too?

Differences between Blast Corps and Blastdozer

Promotion Cutscene

International	Japan

Due to the game's different names, the star has "BD" on it in the Japanese version and "BC" elsewhere.

Backlash

International	Japan

Due to the game's different names, the Backlash has "BD" on it in the Japanese version and "BC" elsewhere.

Blast Corps Semi

International	Japan

Again, due to the game's different names, the semi's logo says BLASTDOZER in the Japanese version.

Platinum Medal

International	Japan

Once again, due to the game's different names, the platinum medal has "BD" on it in the Japanese version and "BC" elsewhere.

American Version (v1.1)

The updated US version patched a somewhat infamous glitch which involved parking a vehicle next to a destructible object/building so the player cannot exit said vehicle (denoted by a "D'oh!" sound when pressing Z to exit). Pressing Z multiple times would automatically destroy the building or object, including those that require TNT crates to be pushed into them.

Japanese Version

The Japanese version not only patched the Z-trigger glitch, but increased the platinum medal time attack requirements for several levels. Other text and aesthetic changes were also made, although the text scrolls the same speed regardless of language.

(Source: http://www.blastcorps.us/)

European Version

Along with patching the Z-trigger glitch and adding a language select, all medal times were increased by 20% and the game's refresh rate is 20% slower.
