GAMEPLAY IMPROVEMENTS
Dragon's Lair Enhancement 2.1 enhances the gameplay of original arcade version of Dragon's Lair (Cinematronics 1983).  The new ROMs reorganize the flow and structure of the gameplay by putting a logical order to the "rooms".  These ROMs access all the footage on the Laserdisc including the new prototype footage found on the Dragon's Lair Limited Edition Laser Disc that was pressed in 2002.  Finally you'll get a chance to play all new rooms, new moves and new choices.  Play Dragon's Lair the way it was intended to be played.

Dragon's Lair Enhancement exists thanks to some great efforts by some great people.  Their hard work and dedication made this project a reality.

DRAGON'S LAIR ONE!
Here is the commented disassembled code from the very first (?) prototype of Dragon's Lair--Dragon's Lair #00001.  Thanks to Matteo Marioni and Jason Finn for the ROM dump.  Search for "DL1" to find areas were this ROM was noticeably different than rev D.  Note:  Data for moves and scenes was most likely different so in the interest of just comparing gameplay this data was removed.
