Dragon's Lair - Diagnostics Manual & ROM Images (USA / Cinematronics) (30 pages)

* Revision A, B, and C EPROMs use the Pioneer PR-7820 only.  Revision D EPROMs use the Pioneer LD-V1000 only.  Revisions E, F, and F2 EPROMs use either player.  Revisions A, B, C, and D are a five chip set.  Revisions E, F, and F2 are a four chip set.

** Beta 1 and Beta 2 are a five chip set for use with a Rev A PCB and use the Pioneer PR-7820 only.
Beta 1 came from Dragon's Lair cabinet serial #1.  Beta 2 (previously named Rev X) was renamed because it was noted that it plays the same as Rev. A, B, & C, but the code is different from all other ROM revisions.

Standard LD-V1000 firmware required - The LD-V1000 players that were used in the game Badlands contain firmware that was modified by Konami.  The EPROM in these players must be restored to Pioneer's original firmware to work in Dragon's Lair.
Download the standard Pioneer LD-V1000 EPROM image.

Conversion Cards - None of the original laserdisc player models are natively compatible with any other model, making direct substitution impossible.  Several products have been developed over the years to allow replacement/upgrade of the laserdisc player.

Dexter is the newest product.  Unlike the other products below which convert to a newer laserdisc player model, no player or disc is needed with Dexter.  The Dexter board is a drop-in replacement which poses as a laserdisc player and plays the video for the game digitally, from a custom file format without video compression.  Dexter accepts the original commands from the PCB through the original interface cable.  Dexter has been going in and out of production multiple times, per demand, via pre-order process only.

LaserCon is a laserdisc player conversion card that allows any of the above mentioned Pioneer and Philips laserdisc players to be replaced with newer supported Pioneer players.  The original LaserCon is no longer in production.

Also from LaserCon, Merlin-8000 is a MultiROM board that performs laserdisc player model conversion at the source, by altering the communication protocols within the Dragon's Lair ROM, as opposed to intercepting and then converting the original signal outputs, which costs processing time.  Multiple Pioneer models are supported.

The Hi-Tech conversion card allows the original Pioneer laserdisc players to be replaced with newer Sony laserdisc player models.

The LaserAce conversion card allows the game to use a variety of different Pioneer and Sony laserdisc players.  LaserAce is no longer in production.

PC Conversion - This do-it-yourself document instructs how to install a desktop PC, and the accompanying software download, into your game cabinet to convert it from the Pioneer LD-V1000 to a Sony laserdisc player.



Merlin MultiROM - Merlin is a direct replacement for the original EPROM board used in Dragon's Lair and Space Ace.  It includes Dragon's Lair rev F2, Space Ace rev A3, DLE, SAE, and optionally, DL2E.  Merlin allows ROMs to be swapped by using the joystick and button.  For more information, check the LaserCon page.

Board Revisions - Two different board revisions existed. (revision A and revision C)  Revision A PCBs have a serial number below 6,000 and revision C PCB's have a serial number above 6,000.  PCB revision C was when the switch was made from revision D EPROMs (five chip set) to revision E EPROMs (four chip set).  This is also where the switch from the PR-7820 to the LD-V1000 started.  Older boardsets below serial number 6,000 (rev A PCB) can be modified to use the LD-V1000, and newer boardsets above serial number 6,000 (PCB rev C) can use the PR-7820 with a slight modification.  For instructions on what needs to be modified as well as a detailed look at the way both of these laserdisc players communicate with the main logic board, check out Jeff Kulczycki's Logic Board Conversion

Sometimes when the EPROMs were changed from the five chip set to the four chip set, the 5th chip, (now unneeded) was left in, making it hard to determine what revision is being used.  If your EPROMs are unlabeled, the best way to determine what revision they are is by changing dipswitches.  EPROM Rev E, F & F2 can't do 4 coins per credit, so that setting makes a good test.

Changes in EPROM REV. E, F, & F2 - The switch for joystick feedback sound (B3) is discontinued and is now used to select the model of disc player. If you are using a LD-V1000 player and set this switch in the PR-7820 position, the LD-V1000 will play the disc from beginning to end after power-up, and the game will not function. If you are using a PR-7820 player and set this switch in the LD-V1000 position, the game will not reach its second beep after power-up, and the screen will remain blank. (Note that along with the proper setting of switch B3, the correct main circuit board appropriate for the disc player in use must also be installed for the game to work.)

The option for 4 coins per credit is discontinued, and this switch (A1) is now used for difficulty setting selection. The difficulty level of hard can be upgraded to very hard with this switch. Very hard difficulty is characterized by a few specific scenes that have been reprogrammed so that they require extremely critical (and occasionally abnormal) timing on the part of the player. These critical scenes will randomly appear during the game at times when they arent supposed to, replacing the scene that would have otherwise appeared at that point. If a player can recognize that a certain scene should not normally be appearing at that time in the game, he can conclude that it is the very hard version of that scene and play it accordingly, if he knows how. Occasionally however, a critical scene will appear at the right time to replace itself as a normal scene, making it impossible for the player to distinguish right away whether it is the normal version of that scene, or the very hard version. Aside from these specific, critical scenes, the remaining scenes of the game are of hard difficulty.

A setting of 2 coins per credit is not required for pay-as-you-go to function. In pay-as-you-go mode, the price to continue the game is the same as the price per credit, either 2 or 3 coins. Note however, that if the game is set for pay-as-you-go at 3 coins per credit, the screen graphics will incorrectly ask for only 2 coins, both to start the game and at the interruption points.

In pay-as-you go mode, extra lives may be awarded after interruption points only if the game is set to begin with 3 lives.

The difference between rev. F and F2 was a small change in U4 to correct a bug on the second move in the Dragon's Lair scene.  On rev. F EPROMS, making no move on the second move of the Dragon's Lair causes the rest of the scene to play by itself.  Actually it throws the game into a loop, and after so many seconds of inactivity, the game detects this and resets itself.

European Versions - Dragon's Lair was licensed to Atari for production and manufacturing in Europe.  The cabinet was very similar to the Cinematronics release, but the hardware, including the laserdisc player was totally different.  Atari sub-licensed Dragon's Lair to Sidam for production and manufacturing in Italy.  Most of the hardware for the Sidam version was the same as the Atari version, but the cabinet design was totally different.  Both the Atari and Sidam versions of Dragon's Lair used video overlay for the score and lives rather that the score display PCB that is used in the Cinematronics version.  Click on the following links to see screen shots of the video overlay.  Image 01 | Image 02

Enhancement ROMs - These ROMs make use of the laserdisc's full potential.  Check out Dave Hallock's Dragon's Lair Enhancement.

Monitor Swap - If the monitor in your Dragon's Lair, Space Ace, or Thayer's Quest is not up to your liking, you can replace that monitor with a 19" TV.  The Monitor Swap Tech Page will show you everything you need to know.

68705 Bypass Mod - Update for older Rev. A DL/SA PCBs.  See the 68705 Bypass Modification Tech Page for more information.

Volume Control Hack - Shaun Wood comes thru with a neat hack for the "move beeps" in Dragon's Lair or Space Ace.  Now you can adjust the move beep volume if it is too loud or soft for your environment.  Check one Shaun's Dragon's Lair Volume Control Hack.

Interchangeability - Space Ace can be played in a Dragon's Lair cabinet simply by changing the laserdisc and the EPROMS (and also ideally with the installation of the 3 skill level selection buttons for "Cadet", "Captain" & "Space Ace").

Engineering Mode - Engineering mode was designed to let the engineers play-test a scene without having to play through the whole game.  To learn more about this, check out Jeff Kulczycki's info on the Engineering Mode for Dragon's Lair.

Initialization - Ever wonder what all those characters are in the score display of Dragon's Lair while the game boots up?  Check out Jeff Kulczycki's Dragon's Lair Initialization page.

LD-V1000 Boot Switch - A simple inexpensive way to build a switch that issues a play command to the LD-V1000 or LD-V1001.  Check it out here.

Scene Sequencing - For a detailed look on the random order of the scenes for Dragon's Lair, check out Dave Hallock's Dragon's Lair Scene Sequencing.
