DRAGON'S LAIR ENHANCEMENT ROM SET VERSION 1.1 - February 29, 2000
Created by Dave Hallock

INTRODUCTION

These ROM sets have been edited to enhance the gameplay of Cinematronics' 1983 arcade version of Dragon's Lair by utilizing the laserdisc's full potential.  The methods that the original program employed to shorten scenes and keep gameplay brief have been eliminated.  Some logical reconstruction to game organization and presentation has been implemented, and some new choices and branching during gameplay are possible, all without radical change or dissimulation from the overall original game structure.  Also, a handful of typos in the original data that negatively affected game performance have been discovered and corrected.

View the list of the main enhancements that these ROMs provide (surprises revealed).  Full disclosure of all changes is included with the download.

ROMS

There are two ROM sets; each set contains four ROMs.
Set DLE_11_P is optimized for use with the PR-7820 laserdisc player & rev. A boardset.
Set DLE_11_L is optimized for the LD-V1000 player & rev. C boardset.

The only difference between the two ROM sets is how values of time are defined.  Different disc player & boardset combinations behave differently.  Each ROM set has been fine-tuned for its hardware configuration specified above; however, both new ROM sets will function with any configuration and play the same game.  If you are using a rev. A boardset with a LD-V1000, or a rev. C boardset with a PR-7820, it is recommended to use the ROM set optimized for your disc player.  If you are using any other newer model of disc player, you should probably use ROM set DLE_11_L, but only trial & error will determine which set works better for you.  Dragon's Lair uses type 2764 EPROMs or compatible.

VERSION

DLE version 2.1 is now available.

DLE version 1.1 replaced DLE 1.0 by restoring all of the game difficulty options found in the revision F dipswitch settings chart.  DLE 1.0 only functioned correctly with the easy difficulty setting.
