This is a sub-page of Proto:Crash Bandicoot 2: Cortex Strikes Back.

Hiddenpalace.org logo.png  This prototype is documented on Hidden Palace.

The September 29th, 1997 prototype of Crash Bandicoot 2: Cortex Strikes Back is a review version of the game dated a few weeks before the final NTSC-U release version. It was released on May 1st, 2021.

Cheat Features

Warp Room Codes

In the warp room, three button combinations can be inputted:

  • Press Right, Down, Down, Left, Down, Circle, Square, Triangle = Give all colored gems, unlock the elevator, and open all secret entrances.
  • Press Right, Down, Down, Left, X, Circle, Circle = Trigger the hologram cutscenes by pressing R2. They will play in chronological order of appearance (except for the annoyed Cortex easter egg scenes and the two Brio scenes, which are the last ones).
  • Press Right, Down, Down, Left, Down, Circle, Triangle, Circle = Turn off active cheats.

A life sound effect will play upon entry.

General Differences

Modification dates on the files are identical to the final NTSC-U version, suggesting the dates in the final game are inaccurate. Therefore, it is not possible to estimate what the approximate build date of the final release might have been, although one can safely assume that it was sometime in October.

Startup

Sep 29 Final
  • The sound that plays in the Naughty Dog screen is different.
  • The "Demo" notice in attract mode only appears in Sewer or Later, Bear It, and N. Gin demos, although the text is black and doesn't flash.
    • Demo inputs are different.
    • After the attract ends, it returns to the startup screens.
    • Skipping the attract will put the player into the warp room, rather than returning to the title screen.

Gameplay

Crash2 Sep29 CrashInvincibilityFrame.png
  • Music volume is defaulted to 75% as opposed to 100% in the final game.
  • The bonus round music tracks don't loop properly and they just start over.
  • Crash's invincibility frames that flash after taking damage or during Aku Aku invincibility is white in this version.
    • His back and part of his shoes textures are not affected though, causing to remain unchanged while the rest of his body is flashing white.
    • Aku Aku also change colors during this state, featuring colorless feathers, white nose, and bright body.
    • Like in Crash Bandicoot, Aku Aku flashes when Crash takes damage as well.
  • There are no sound effects for warp room actions, such as when Crash dances, rolls out, or takes items out of his pocket.
  • Skipping Crash's dances will also skip the hologram cutscenes.
  • Leaving a level prematurely after collecting the crystal or gem will make Crash leap out triumphantly of the portal even if he has earned nothing.
  • If you have any crystals or gems, and use a secret exit, Crash won't take them out of his pocket in the warp room.
  • The gem of secret levels will be invisible when Crash takes it out of his pocket in the warp room.
Sep 29 Final
  • Polar makes a very different sound.
  • Touching a bounce crate above Crash while he is performing a body slam will collect the Wumpa fruits, rather than automatically breaking the crate regardless of how many bounces are left.
  • You need to hold L2 instead of Triangle to replay a boss fight.
  • Holding down R2 allows you to skip boss fights when going to the next warp room. Attempting to skip the final battle will softlock the game, though.
  • If Crash is awarded an Aku Aku mask upon entering a level while also carrying two masks, he will be able to start the level with invincibility.
    • The game will crash when attempting to load Jet Pack levels due to the missing invincibility form code, as you normally can't become invincible in these levels.
  • Locked crates always provide a single Wumpa fruit which is also picked up instantly, rather than dropping the pickup out of the box.
    • They are immediately counted when the crate is broken, rather than moving to the HUD.
  • Locked crates cannot be instantly destroyed with Aku Aku invincibility.
  • The death route platform moves very quickly.
  • Boost pads only trigger if you run or stand on them - spins and slides make them useless.
    • Running on them during the invincibility frames state does not trigger either.
  • Performing a slide spin when passing through electric fences won't harm Crash.
  • When losing a mask after being electrocuted, Crash won't act as if he had been hurt by jumping up in pain shouting "ouch".
  • Crash can still be electrocuted by electric fences while invincible.
    • If the invincibility ends while he still in the electrocution state, he won't lose the mask.
  • In the pause menu, the analog calibration option is called "Analog Pad" instead of "Calibrate".
    • There is no screen centering option.
  • Leaving a boss level prematurely or loading a save file right after having defeated them will make Crash spawn in the current warp room of the boss, rather than the first level of the next one.
  • Quitting the game will return to the startup intros instead of the title screen.

    • The cutscene replays every time you respawn.
  • If you enter the fight with two masks, you'll get temporary invincibility.
  • Instead of dodging Komodo Joe's spin attack, Crash is additionally able to spin on him while spinning in order to push him away - although unlike earlier builds, this feature is less intuitive here, as the player is more prone to be hurt in the process.

Sep 29 Final

  • A few cylinders on the left corner of the scenery at the beginning of the green gem path are missing.

Soundtrack Differences

Hmmm...
To do:
Upload clear versions.

One of the biggest differences is the music. Almost all levels have slightly different music tracks:
