Crash Bandicoot is more or less one of the killer apps for the PlayStation.

Over the years, the nitty-gritty of Crash's production and technology has been relatively well documented thanks to co-creator Andy Gavin basically publishing the game's floor plan. The game was the product of fighting with limited technology and codifying 3D platformers and would later be tweaked across regions. Bits and pieces of the game would fall through the cracks, including an otherwise finished level called Stormy Ascent.

Password Test Screen

In the title/map/options/etc. level, if the game screen (GOOL global 18) is set to 14 (memcard screen) and GOOL global 1 is set to 10, a password test screen can be accessed, meant to test the integrity of the password encoding and decoding system. Spoiler alert, the password system functions perfectly. Once this screen is entered, you cannot leave it, as none of the buttons do anything.

The password test involves generating a random set of game stats, encoding them into a password, generating the inputs for the password using an "auto-password" system used exclusively for this test, type in the generated inputs, decoding the password, and seeing if the stats came out the exact same. The game tries to test one password per frame, but since the whole process runs through a lot of code and heavy operations, the game can only test around 20 passwords per second. The test runs forever, and if a trial fails then a few "no operation" instructions execute and the test simply stops running. Despite the instructions given, no text is printed to the console (no, not your game console) if an error occurs.

Since the game tests any combination of the 26 gems, any combination of the 2 keys, and a random amount of levels from 0 to 26 (even though the actual game has 30 on the main path), the total amount of different passwords it can test is 7,247,757,312. This will take forever.

Also, the "TESTING PASSWORD SYSTEM" title flashes.

Unused Levels

Stormy Ascent

Stormy Ascent is one of the most infamous cut levels from the Crash Bandicoot series. Originally meant as the final level of the game, it was later cut mostly due to its brutal difficulty.
To access it, use this GameShark code to boot into the level:

US	EU	JP
D0011DB2 3404 30011DB0 0022	D0011DD2 3404 30011DD0 0022	D0011DFA 3404 30011DF8 0022

Programmer and Naughty Dog co-founder Andy Gavin provided commentary for its exclusion from the final version:

"It was too hard and we didn't have time to make it easier. I wish we had put it in as some kind of Easter egg, as it was an awesome level, one of my favorite in the game. Long, a bit brutal, but it looked great, and had a real rhythm to it."

The level is available as DLC in the remake.

Cavern Grotto Level

An eye-catching subterranean environment, this unused level was present (and also unused) in the disc of the April 8 prototype build. While all of its assets still exist on retail copies, and remain unchanged from the April 8th build, the game freezes when forced to load the level due to its older format, rendering it unplayable. The footage of the level shown above is therefore taken from the prototype. Its level ID is 04.
The level features a unique entrance not replicated anywhere else in the game, where Crash spawns airborne, and descends onto the scenery as if he had fallen down from above ground. However, the level itself is unmistakably unfinished - there are no obstacles or enemies present in this level, and the cave located across the wide acid pit leads nowhere, rendering it impossible to finish the level. There are various old fruits laid across the path, but do not appear as they refer to removed objects.

Bonus Round

An unused bonus round level, meant for super long bonus rounds, of which there are none in the game, meaning you'll need an invincibility or similar cheat to get to the end. It has been left in a vastly incomplete state, with wrong outdated textures and old files, such as the crystals at the start having wrong textures and Crash's warp in effect being rainbow-colored. Tawna is meant to be waiting at the end, but missing files will make her crash the game instead. It has a similar layout to the Brio bonus rounds, with different colors, and files for Brio are also present. It contains old versions of the code files WillC (Crash), FruiC (fruit and pickups), DispC (HUD and bonus round selection), ShadC (shadows and boss health meter), DoctC (witch doctor Aku Aku), BoxsC (boxes and explosion particles), WarpC (warp out), KongC (Koala Kong boss), BonoC (bonus rounds), GamOC (general game progress) and CardC (memory card save/load and passwords).

Unused Ending Epilogues

To do: Check the North American version.

The normal ending after defeating Cortex was originally meant to, similarly to the ending in "The Great Hall", play a series of epilogues with each of the six boss characters. This cutscene-level has all the data needed for epilogues and even specific (placeholder) text for it, but the normal ending cutscene simply never plays them. With hacks, the epilogue can still be played just fine. The reason for their (partial) removal is unknown, possibly to make 100% completion have at least some sort of unique reward. In the Japanese version, the Pinstripe and Cortex epilogues have their translated level name as the title, possibly by accident/coincidence.

Unused Screen Offset Variables

GOOL globals 44 and 45 set the horizontal and vertical offset of the screen projection respectively, and are completely unused besides being set to zero on boot. The vertical screen shake also offsets the screen projection, but is stored separately.

Oversights

River Fish Shadow Oversight

The fish in the levels "Upstream" and "Up the Creek" spawn a shadow, but it never appears in-game because the fish never set their shadow flag.

Normal	Fixed

Ripper Roo Shadow Oversight

Ripper Roo spawns a shadow in his boss fight, but it never appears in-game because the shadow flag is never set.

Normal	Fixed

Pinstripe Boss Generator Oversight

Due to an oversight in how the screen shake variable is checked, at the end of the Pinstripe boss battle when Pinstripe shoots the generator, the screen is moved up slightly and then back down after a few seconds. The original intent is to keep the screen shaking until the boss ends and Crash celebrates, which looks very nauseating anyway. The oversight happens in this piece of code for the generator (shown as Lisp pseudocode):

(if (< SHAKEY 0)
  (setf SHAKEY 4.0)
  (setf SHAKEY -4.0)
  )

At first, SHAKEY is set to -4. After the game finishes setting up its graphics matrices using the -4 value, it automatically flips the sign of SHAKEY and sets it one value closer to zero (in this case, -4 becomes 3). On the next frame, this code runs again: SHAKEY is not lower than zero, so it is set to -4. The game uses -4, sets it to 3, etc.. At the end of the boss fight, the value is set to zero, returning the screen to normal. This can be fixed if the branch condition is flipped.

"Lights Out" Sky

• 
• 

The level "Lights Out" actually has a sky, meant to be seen when Crash takes the yellow gem platform up and outside the castle. Unfortunately, this nice view is never seen in-game as the model for the sky isn't set to ignore the natural darkness of the level. Oops.

Unused Scenery

Ripper Roo Offscreen Platform

Just slightly off-screen in the Ripper Roo level, there is a platform on the side of the waterfall that is slightly offset. The idea that Crash would directly climb up the waterfall was explored in a scrapped level which was made much earlier in the game's development.

Sunset Vista Last Floor

The last floor of "Sunset Vista" continues well after the point where the level normally ends. The world geometry gets progressively more incomplete and less textured. The collision and camera function properly, but there isn't exactly much to stand on. There is an invisible wall at the far right edge at the end.

Unused Sounds & Sound Oversights

The generator that is destroyed in Pinstripe's boss battle plays a sound that is played at such low volume that it is nearly impossible to hear in-game.

The sound of the boomerang hazard in the level "Whole Hog", itself not used in the final game.

The Japanese sound effect for Brio getting hit (the English version being a sort of "doh!") plays at a stupidly low volume in-game and is therefore inaudible.

Unused Music

To do: Demonstrate a recording of them in-game.

Four music tracks contain leftover note data that do not play a sound, either by accident or due to technical constraints.

Level	In-Game	Fixed	Difference
Ripper Roo			The most notable difference here. These include leftover snares, crash cymbals and hi-hats. They are present in the "pre-console" version (volume warning).
Koala Kong			Contains missing Cymbal instrument.
The Great Gate / Native Fortress			A flute sample heard towards the end of the track, later used in Crash Bandicoot 2 Jungle levels. This was present in the "pre-console" version.
Heavy Machinery / Castle Machinery			Includes missing Hi-Hats.

Unused Bonus Round IDs

The way bonus rounds work is that the game chooses a bonus round ID and the bonus round level separately. Each of the bonus round levels is split up into four sections, and each section spawns a set of objects (boxes) according to the bonus round ID. Even though all bonus round levels have four sections, the ending may be after the second, third or fourth sections. This means that you can play a bonus that's normally a Brio bonus in the Cortex bonus level or the long Tawna bonus level. There are five bonus levels in the game, one of which goes unused:

• 24: Short Tawna bonus (2 sections long).
• 25: Brio bonus (3 sections long).
• 26: Unused bonus (4 sections long).
• 33: Long Tawna bonus (3 sections long).
• 34: Cortex bonus (3 sections long).

Bonus round IDs are also not linearly mapped to levels. Which bonus level Crash gets teleported to and which bonus round ID to use is determined in DispC, based on which type of pickup Crash has collected 3 of and the level you are in.

Pickup	Level	Bonus ID	Bonus Level
Tawna	Jungle Rollers	0	33
	The Great Gate	4	34
	Upstream	10	33
	Rolling Stones	8	34
	Native Fortress	1	33
	Up the Creek	11	34
	The Lost City	12	33
	Temple Ruins JP version only.	28	33
	Road to Nowhere	13	34
	Sunset Vista	5	33
	Heavy Machinery	18	33
	Cortex Power JP version only.	27	33
	Generator Room	2	33
	Toxic Waste	6	33
	The High Road	3	34
	Slippery Climb JP version only.	29	33
	Lights Out	16	34
	Jaws of Darkness	17	34
	Castle Machinery JP version only.	26	33
	The Lab	19	33
	(default)	0	33
Cortex	Sunset Vista	9	34
	Jaws of Darkness	15	34
Brio	Rolling Stones	14	25
	The Lost City	7	25
	Heavy Machinery	21	25
	Slippery Climb	20	25

"Lights Out" does not have any Tawna pickups in it, so bonus round 16 goes unused. In the Japanese version of the game, 8 new bonus rounds are added, and bonus rounds 22, 23, 24 and 25 are not used.

Code Revisions

To do: Document.

Code for one object may not be the same across levels.

Dummy Files

Every version of the game contains dummy files to pad out the game's disc content, claimed by a developer of the game to be an anti-piracy/online download tactic . The European and North American versions of the game contain the file ZBSPTREE.WAD, which is a little over 300MB in size and is filled with useless garbage data. The Japanese version of the game contains the files ABSPTREE.WAD, the same size as the previous file, and ZTAIL.WAD, a 40MB file filled with zeros. The game never checks for any of these at any point, and thus they can be safely removed. The moral quandary here is whether you want to harm the integrity of your game or not...

Executable Text

To do: Some completely unused text and some other interesting things.
