* Revision A, B, and C EPROMs use the Pioneer PR-7820 only.  Revision D EPROMs used the Pioneer LD-V1000 only.  Revisions E, F, and F2 EPROMs used 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 Serial #1 machine owned by Jason Finn.  Beta 2 (previously 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.

Different EPROM for LD-V1000 - This EPROM is needed if you are using an LD-V1000 that was previously in a Badlands.  You will need to change the EPROM inside the LD-V1000.  Download the Pioneer LD-V1000 EPROM here.

Conversion Cards - LaserCon is a Laserdisc player conversion card for Dragon's Lair (both USA/Cinematronics and Europe/Atari versions).  You can replace any of the above mentioned Pioneer and Philips laserdisc players with newer supported Pioneer laserdisc players.  For more information, check out the LaserCon page.

The Hi-Tech conversion card is also for Dragon's Lair (USA / Cinematronics only).  You can replace the original Pioneer laserdisc players with a newer supported Sony laserdisc player.  For more information, check out the Hi-Tech page.

The LaserAce conversion card will let your laserdisc game use a variety of different laserdisc players.  Unfortunately these cards are no longer in production, but can still be found on eBay or the D-L-P Classifieds occasionally.

 

 

MultiROM - The LaserCon MultiROM is a direct replacement for the original EPROM board used in Dragon's Lair and Space Ace.  It includes all of the known ROM revisions for Dragon's Lair (listed above), including DLE 1.1 and DLE 2.1 as well as all of the known ROM revisions for Space Ace, including SAE 1.0.  For more information, check out the LaserCon MultiROM 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 board 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

Home Brew Conversions - A do-it yourself conversion card!  Check out Robert DiNapoli's PC conversion.

Enhancement ROMs - A very cool item to have.  These ROMs have been edited to enhance the gameplay of the (North American) arcade version of Dragon's Lair by utilizing the laserdisc's full potential.  Be sure to check out Dave Hallock's Dragon's Lair Enhancements.

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.

Code Hacking - To learn more about the Dragon's Lair ROM structure, check out Hacking Around the Lair, authored by Robert DiNapoli, Dave Hallock, and Matt Ownby.  Be sure to have your "thinking caps" on for this one :)

Interchangeable - Space Ace can be played in a Dragon's Lair cabinet simply by changing the laserdisc and the EPROMS.

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 scoreboard 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 your LD-V1000 or LD-V1001Check it out here.
