- 12th December 2006: Aaron Giles - I'm looking for someone, preferably in the U.S., who owns an original Dragon's Lair laserdisc and is willing to loan it out for a couple of months. Either contact me via my webform (, or reply to this post. Thanks!

Going up to lossy with medium deltas (up to 4/256 per component) gets you closer to 4:1 and 5:1 compression with almost no visible difference. Increasing the max deltas beyond that helps further with compression, but it definitely starts to become visible. Not everything is nailed down yet, and it will probably take a couple of months to materialize, but those are the basics. The first game I'm looking at is obviously Dragon's Lair, but coincidentally, I just received in the mail a driver for the American Laser Games series ( of shooters as well, which were all run on an Amiga 500 with a genlock. Fortunately, the Amiga emulation is pretty decent these days, so things are progressing well there. Now that the basic system is up and running, I'm hoping others can help get the rest of the laser games moving forward. In 0.110u4 I included support for a couple of common laserdisc players. Even though you can't see any video yet, you can at least watch their operation to see if things are working properly. In 0.110u5 I'll have support for the Sony LDP-1450 ( laserdisc player and the ability to display dummy frames (each frame is solid color and gets a unique Cb/Cr value) so that you get a little better sense of the operation. And hopefully in the next month or so, I'll have the first video running at last...

- 0.110u4: Added Dragon's Lair (US Rev. F2) and clones (US Rev. A, Pioneer PR-7820), (US Rev. B, Pioneer PR-7820), (US Rev. C, Pioneer PR-7820), (US Rev. D, Pioneer LD-V1000), (US Rev. E) and (US Rev. F). Removed the old Dragon's Lair version. Aaron Giles rewroted the Dragon's Lair driver from the schematics. Added new module machine/laserdsc.c which has laserdisc emulation for the PR-7280 and LD-V1000 laserdisc players. Full emulation of the laserdisc is pending support for CHD audio/video and high quality rips, but you can operate the game and see the frame numbers that would be displayed. Added built-in layout to display the scores, lives and credit information. Changed Z80 clock speed to 4MHz, VSync to 48Hz and added AY8910 (2MHz) sound. Added dipswitches 'Coinage', 'Difficulty Mode', '2 Credits/Free play', 'Lives', 'Pay as you go', 'Diagnostics', 'LD Player', 'Sound every 8 attracts', 'Demo Sounds', 'Unlimited Dirks', 'Joystick Feedback Sound', 'Pay as you go options' and 'Difficulty'.

- 1st September 2001: Mirko Buffoni added support for the Dragon's Lair video. However, it only works with the DVD-ROM version and only in Windows, so inclusion is unlikely.

- 0.35b13: Nicola Salmoria added Dragon's Lair (Cinematronics 1983) (Testdriver).
