Please find the chart for your matching firmware for your matching Merlin model at the LaserCon site.

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 Space Ace.
Download the standard Pioneer LD-V1000 EPROM image.

Conversion Cards - The original Pioneer PR-7820, Pioneer LD-V1000, and Philips 22VP932 laserdisc players are not 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.  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.

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 site.

European Versions - Space Ace was licensed to Atari for production and manufacturing 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 manufacturing in Italy.  Most of the hardware for the Sidam version is the same as the Atari version, but the cabinet design is completely different.  Space Ace ('91) was licensed to Atari for production and manufacturing in Europe.  Atari sub-licensed Space Ace ('91) to Elettronolo for production and manufacturing in Italy.  Most of the hardware for the Elettronolo version was the same as the Atari version, as well as the cabinet itself.

DIP Switch Remap - With this replacement ROM image, your Space Ace DIP switch settings will be more closely matched to Dragon's Lair.  Also, the skill level selection can now be set via DIP switch.  See the Space Ace DIP Switch Remap page.

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.

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.  Check out Shaun Wood's Dragon's Lair Volume Control Hack.

Interchangeability - Dragon's Lair can be played in a Space Ace cabinet simply by changing the laserdisc and the EPROMS.  Dragon's Lair II had a conversion kit for Space Ace ('91).  The kit included a Space Ace ('91) laserdisc, control panel overlay, marquee, two "fire" buttons, and one EPROM containing the Leland ROM image above.  The animation stored on the Space Ace ('91) laserdisc is the same as the original Space Ace ('83) version, 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 play-test a scene without having to play through the whole game.  To learn more about this, see Jeff Kulczycki's info on the Engineering Mode for Space Ace.

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.
