The laserdisc players of the 1980s often had command protocols and/or features that were unique to each model. This means that it's usually impossible to directly swap out an arcade game's original laserdisc player for a newer and more reliable model. Standards that allowed compatibility between models came later.

Several commercial products have been developed over the years specifically to allow the laserdisc players in arcade games to be replaced/upgraded. If you are looking to find a newer substitution for an original laserdisc player, or if you are just trying to determine whether your game already had a conversion installed into it before you got it, all of these products are shown below.

Additionally, some freely downloadable conversion methods that use either a desktop PC, or modified ROMs, or other components are listed in the "Disc Player Info and Conversions" section of our main Tech Center.

It is needlessly redundant and potentially error-prone for more than one of the following to be connected to a game at the same time, even though the game may be able to function that way.

This line reconfirms the current prices shown on this page as of December 26, 2022.
The Dragon's Lair Project website does not sell these products. This list is a reference.

Dexter is the newest product. Unlike the other products on this page which convert to a newer laserdisc player model, no player or disc is needed with Dexter. Dexter plays the video for the game digitally from a custom file format. Dexter accepts the original commands from the game's PCB through the original interface cable.
