Back in 1993 SEGA showed off the SEGA Genesis version of Aladdin during the C.E.S show in Chicago, this was a early prototype showing off what players can expect when Aladdin hit store shelves during the 1993 holiday season.According to Hidden Palace wiki, differences between Aladdin’s Chicago C.E.S demo compared to the retail versions are:

A lot of levels have enemies either missing from the final or incomplete pencil tests.

The level music for Level 2 “The Desert” is a completely different tune that was cut from the final. It’s based on a track from Jungle Book.

Aladdin’s lives icon looks different.

The “Inside the Lamp” level is completely different from the final. Instead of going all the way to the right of the level, the player instead has to reach the very top by riding on Genie bowling balls and jumping on springs. A lot of graphics appear that are not in the final iteration of the level.

The final level uses a different background.

The Aladdin’s Chicago C.E.S demo was dumped thanks to the user Billscat-socks, who has also dumped a ton of different prototypes. Its thanks to users like him that the retro scene gets all these interesting prototypes and we get to see changes made in prior versions. You can download Aladdin’s Chago C.E.S demo below.
