Proto:Disney's Aladdin (Genesis)

This page details one or more prototype versions of Disney's Aladdin (Genesis).

  This prototype is documented on Hidden Palace.

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

This early build of Aladdin, as the in-game text would suggest, was used for demonstration purposes at the Consumer Electronics Show. However, Summer CES 1993 occurred on June 3-6 whereas the date on the debug screen is June 27, so it's likely this build was further developed from the actual CES build and wasn't actually presented on the show floor.

This build was dumped in 2016, and then later officially released in 2019 as an extra in Disney Classic Games: Aladdin and The Lion King.

To do: So, so much more.

ROM Header

At this point in development, the build uses a placeholder "The Jungle Book" header with a date of September 1993.

Opening Screen

Upon booting up the game, you're greeted with a debug screen that looks and functions nearly identically to the one seen in the final game.

• CHEAT MODE - Player is invincible.
• START ON LEVEL - Level select.
• FREEZEABILITY - Holding Start will freeze the game in place, likely for use in taking screenshots. (Pressing Start normally will return you to this screen.)
• MAP VIEW MODE - Freely move the camera throughout the level. Moving the camera too low will cause you to lose a life.

On the top, it reads NTSC if you are playing on a NTSC console or PAL.

• RAM BYTES USED - Calculates the amount of RAM Bytes that are used.
• RAM BYTES LEFT - The amount of RAM Bytes that are left.

To be clear, maximum amount of RAM is 65536 Bytes.

• ROM BYTES USED - Calculates the amount of ROM Bytes that are used.
• ROM BYTES LEFT - The amount of ROM Bytes that are left.

Adding both together will form the maximum amount of ROM Bytes, 2097152.

• MAX TILES TO MAKE MAP - Maximum amount of tiles to make maps.

The entire text can be seen at offset 001359B0 to 00135E10.

Crash Handler

A crash handler for when things break, showing the error that was encountered, current values of some registers, and a request to fax the error message for further debugging.

• It has the date of 16th January, 1991, which is nearly 2 years before it was released, possibly for internal testing.
• D.P. is the signature of David Perry.
• A list of errors can be found at offsets 001B4840-001B4B50.

Sega Screen

Proto	Final

In the prototype, Genie is dressed as a cheerleader like in the movie waving his arms around. In the final version, Genie is dressed as a referee with a starter pistol and stopwatch. Genie shoots the gun, starts the watch, and accidentally hits Iago, who plummets to the ground with a flurry of feathers.

Level Intros

Most levels have an introductory cutscene. The character portraits were mostly redrawn and the dialogue was rewritten to actually make some sense. In the prototype, all cutscenes use the Cave of Wonders entrance for the background, whereas the final game uses a variety of different backgrounds. The entire in-game text can be found at addresses 00135E10 to 00136C30.

Cut Enemies

Two enemies were cut from the final game. These include a sword throwing enemy who grabs a sword from his throat in the Agrabah Market and a prisoner trying to cut off his shackles in Sultan's Dungeon.

The Prisoner was refined prior to the final release before he was cut. However, the ROM for the Final Cut used in for the Disney Classic Games Collection has his finalized sprite inserted into the code, suggesting that there were plans to bring back cut features.

Stages

Demos

• Aladdin acts erratically in the demos. He will get a Game Over on all of the demos if invincibility is disabled, as if it was seemingly intended for an older build of the game.
• The demo cycle is as follows: Argabah Rooftops, The Desert, Sultan's Dungeon, Cave of Wonders, and Rug Ride.
• The amount of crystals, and apples will remain, while the score will reset.

Agrabah Market

• The music is different.
  • Prototype BGM: Friend Like Me
  • Final BGM: Prince Ali
• The end of the stage has a fight with Gazeem rather than towards the end of Agrabah Rooftops.
• The basket enemy has a few frames that are unshaded.
• Iago has an extra frame that goes unused in the final.
• The pot thrower is a pencil test.

The Desert

• The music is different.
  • Prototype BGM: Arabic Ne Naw
  • Final BGM: Camel Jazz
• Aladdin can bypass most of the ruins in this stage.

Agrabah Rooftops

• Due to the fact that Gazeem was fought earlier, he is replaced by a knife juggler.
• Razoul's fight takes place on a staircase rather than in scaffolding. Ironically, the stairs make Razoul easier to defeat as Aladdin can simply jump up the stairs and slash him repeatedly.

Sultan's Dungeon

• The music is different.
  • Prototype BGM: Gloomy Tune
  • Final BGM: Arabian Nights

Cave of Wonders

• The music is different.
  • Prototype BGM: Camel Jazz
  • Final BGM: Gloomy Tune
• The fight with the Shiva Monkey has four teleportation pads rather than two.

The Escape

• The music is different.
  • Prototype BGM: Rug Ride
  • Final BGM: Arab Rock 2
• The boulders look different than in the final. However, this same design was refined in the DOS and Amiga ports.
• The tileset is extremely unfinished and basic.
  • The background is the same as Cave of Wonders, but red, which itself got used in Rug Ride.
  • The platforms are less-detailed, along with the lava.
• The collapsing platforms do work, but unfinished and can cause glitches if collided with solid ground whilst standing on the platform, akin to the v0.02 prototype of Sonic CD. The lava might be semi-solid.
  • In fact, the same platforms are used in the Cave of Wonders level.
• You can't finish this stage.
• Aladdin can walk on lava as solid ground, more akin to Sonic 2's Simon Wai Prototype.

Rug Ride

Very unfinished level, only background, platforms and huge boulders falling from the holes above exist here. Beating this level will send you to the desert level.

Inside the Lamp

The level is a tower that Aladdin must climb up in order to finish. There is no music or sounds. The smoke trails are not semi-solid, so Aladdin must ride on bowling balls in order to get across. There is a head that looks like Goofy from Mickey Mouse at the start of the level.

Sultan's Palace

The fish in this level are placeholder sketches. Beating this level will send you to the desert level. To beat it, you set MAP VIEW MODE to ON, and go left.

Jafar's Quarters

An unfinished version of the level. No enemies spawn and Iago cannot be damaged. Iago will occasionally play his injured animation.

Jafar's Palace

• The level background is different.
• Some of the palace background is missing.
• The floor spikes are curvier and have a gold tint instead of a red tint.
• A lot of floor spikes are absent, many have been replaced with balls and chains.
• Balls and chains also appear where there is nothing in the final game.
• Jafar is present in both his normal and cobra form for testing purposes.
  • Beating this level (Defeating Cobra Jafar in one hit) will send you to the desert level. There is no ending.
• (Human) Jafar and balls and chains have an incorrect palette.
  • The balls and chains were imported from the Dungeon level, which is why it has a incorrect palette.

Unused text

BONUS LEVEL

While the bonus level cannot be accessed using the level select, this text would remain.

DAVID PERRY, YOU CAN CHEAT NOW!

Since the debug menu is activated automatically, this text is never seen as the screen upon activating the debug cheat still exists in the ROM, unused.

• The final version is changed to AH, DAVID PERRY, WHAT IS YOUR WISH?
