What is romcmp?

What is jedutil?

What is chdman?

What is ldplayer?

ldplayer is an optional utility that simply plays the audio and video from laserdisc CHD files. It actually emulates and therefore behaves just like a real laserdisc player - you can pause, fast forward, rewind, and all the rest.

Can I use chdman to put a CHD file back onto a hard disk?

How do I use ldplayer?

First, you need to build the application. This is done by the command: make TARGET=ldplayer.

Secondly, while ldplayer uses the same default inipath as MAME, it looks for ldplayer.ini instead of mame.ini. To preserve your video and other options, make a copy of your mame.ini file named ldplayer.ini.

Next, go to your MAME ROMs folder and make a copy of (the ROMs for Cube Quest). Rename them as

Finally, run ldplayer like this: ldplayer pr8210 -rompath c:\path\to\;c:\path\to\chd\to\play

Note that the first path is the full path to the file and the second is the full path to the laserdisc CHD file you wish to play. There is a semicolon - ; - between them.

Once ldplayer is running, you can hit Tab like usual and check out Inputs (this game) to see the controls. Space is the Play/Pause button, for instance. Note that some laserdiscs (notably Cube Quest) have 30 seconds or more of nothing at the start, so you either need to be patient or use fast-forward to start seeing video.
