Standard LD-V1000 Firmware - The LD-V1000 players that were used in the game Badlands contain firmware that was modified by Konami.

Conversion Cards - The original Pioneer PR-7820, Pioneer LD-V1000, and Philips 22VP932 laserdisc players are not natively compatible with any other model for a direct substitution.  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.  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 the PR-7820, LD-V1000, and 22VP932 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 Space Ace 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.

 

 

Diagnostics ROM Package - To aid with PCB troubleshooting, Shaun Wood offers an improved Diagnostics ROM Redo, which also contains the archive of the original, flawed Cinematronics diagnostics package.

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 DL2E.  Merlin allows ROMs to be swapped by using the joystick and button.  For more information, check the LaserCon site.

Arthur PCB Replacement - Arthur is a replacement main logic board for Dragon's Lair and Space Ace.  The circuitry for the ROMs and the Space Ace annunciator are integrated onto one main PCB.  Arthur also has all the functionality of the Merlin MultiROM products built in.  For more information, check the LaserCon site.

Main PCB Revisions - There are two different Cinematronics PCB revisions (A and C).  Rev. A PCBs were only released with Dragon's Lair but can still be used with or found in Space Ace conversions.  The rev. C PCB arrived when the transition was made from the PR-7820 to the LD-V1000 laserdisc player.  The older rev. A PCB can be modified to use the LD-V1000, and the newer rev. C PCB can be modified to use the PR-7820.  For instructions on how to perform these modifications, including details on the laserdisc player communications, see the Dragon's Lair PCB Conversion Between PR-7820 & LD-V1000 page.

Additionally, to see the multiple modifications that kept occurring to the design of the rev. A PCB during the production of Dragon's Lair until the design was essentially finalized near serial number 5,000, as well as detailed instructions for performing these modifications on early rev. A PCBs to achieve their most stable condition, check the Dragon's Lair Rev. A PCB Modifications page.

European Versions - In 1984, Space Ace was licensed to Atari for production and manufacture in Europe.  The cabinet is very similar to the Cinematronics release, but the hardware, including the laserdisc player, is totally different.  Atari sub-licensed Space Ace to Sidam for production and manufacture in Italy.  Most of the hardware for the Sidam version is the same as the Atari version, but the cabinet design is completely different.  In 1992, Space Ace was licensed to Brent Leisure for production in most of Europe, and to Elettronolo for production in Italy, as conversion kits for their Dragon's Lair II games.  Most of the hardware for the Elettronolo version is the same as the Brent Leisure version, as well as the cabinet itself.

Volume Control Wiring Error - Apparently all Dragon's Lair and Space Ace main wiring harnesses were constructed with an error.  Two pins are reversed in the connector for the volume controls, shorting the right audio channel to ground and creating noise in the system.  For the fix, see the Dragon's Lair / Space Ace Operator Convenience Panel Pinout.

DIP Switch Remap - With the Space Ace DIP Switch Remap ROM made in 2002, your Space Ace DIP switch settings will be more closely matched to Dragon's Lair, so that no switch-flipping is needed after the EPROMs are swapped to change between games.  Also, the skill level selection can now be set via DIP switch, which is helpful when using the Dragon's Lair control panel without the three skill level buttons.

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 it with a 19" TV.  The Monitor to TV Swap page will show you everything you need to know.

68705 Bypass Mod - An update for older rev. A Dragon's Lair / Space Ace PCBs.  See the 68705 Bypass Modification page for more information.

Joystick Sound Volume Control Hack - Now you can adjust the volume of the joystick feedback sound in Dragon's Lair or Space Ace if it is too loud or soft for your environment.  See the Dragon's Lair / Space Ace PCB Volume Control Hack.

Interchangeability - Dragon's Lair can be played in a Space Ace cabinet (1984) by changing the laserdisc and the EPROMS.  Dragon's Lair II had a conversion kit for Space Ace (1991).  The kit included a Space Ace (1991) laserdisc, control panel overlay, marquee, two red fire buttons, button labels, and one EPROM containing the Leland ROM image above.  The animation stored on the 1991 laserdisc is the same as the original 1983 laserdisc, but the discs are not directly compatible with each other.  The video footage is not aligned on the same track/frame numbers.

Engineering Mode - Engineering mode was designed to let the engineers playtest a scene without having to play through the whole game.  To learn more about this, see the Space Ace Engineering Mode 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.  See the LD-V1000 Boot Switch page.
