Conversion Cards - Various 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 or infrared signals.  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 game to use newer supported Pioneer players.  LaserCon is no longer in production.

Technical Notes - The document "Technical Notes on Cliff Hanger" written by James Bright of QuarterArcade.com explains the theory of operation for Cliff Hanger.

Laserdisc Audio/Video Overruns - The Cliff Hanger Overrun fiX ROM set is a 2014 modification that corrects occurrences of laserdisc audio/video playing for too long after the end of all main sequences and death scenes.  An option for unlimited lives has also been added to DIP switch 27.

Interchangeability - Goal to Go can be played in a Cliff Hanger cabinet by changing the disc and the ROMs.  There is also a conversion kit that allows Cobra Command to be played in a Cliff Hanger cabinet.  This kit came with a dedicated Cobra Command PCB and also a laserdisc controller PCB to allow operation with the PR-8210, and it requires an adapter for the wiring harness.
