DRAGON'S LAIR II LASERDISC PLAYER CONVERSION
Written & Developed by Robert DiNapoli - 4 February 2000

INTRODUCTION

Can't find a replacement Sony LDP-1450 or LDP-3600D for your Dragon's Lair II?  Now you can use any Sony LDP series player in your Dragon's Lair II game.

PARTS NEEDED

Modified ROM Image (see download section)

THEORY OF OPERATION

• The Sony LDP-1450 and LDP-3600D support text display.  Other Sony laserdisc players do not.
• The Dragon's Lair II ROM code expects to be able to send certain text commands to the LDP-1450 or LDP-3600D.
• The LDP-1450 and LDP-3600D display the text.  Other Sony players get thoroughly confused.

So, remove the text display routines, and all goes fine...

CONSTRUCTION

Simply burn the attached ROM code into a 27C512 EPROM, and enjoy.  This should work with any Sony LDP series player.  The downside to this hack is that no text will be displayed on screen, even when using a Sony LDP-1450 or LDP-3600D.
UPDATE - For your consideration, Dexter is a fully compatible laserdisc player replacement product.
