Hi, just to update you all. I'm working quickly on this cool project.
Something  similar to Dexter but I use simply raspberry with hw acceleration and pal video @ 10mbits grabbed from Philips laserdisc.
I want to do this for euro version at the moment.
The EVA also translate commands for one ld player to another.
Currently implemented pioneer , working on Sony and Philips .
You can see some of my work here.

This project uses the USB adapter to write and read data to and from the arcade Pcb .
The system implements laserdisc player protocol and send commands to the digital player running on raspberry.
Using mpeg2 video @ high constant bitrate encoded from our laserdiscs. In this special case from one of the last Philips PAL DL.
The comunication between the subsystem is too quick so I'm going to insert delay in some parts to emulate laserdisc player seek speed.
Raspberry has composite ntsc and pal output so we can use it in many games.
As request for spectroman if we have rgbs output we can go straight to the monitor. I'll try it out.
Another request is to do overlay data on video... Quite interesting also for DL2.
Now the system is in tuning to set the right delay in search routine.
I'll finish soon the Sony protocol. Just missing the request of the position as address in frame.
Next Philips protocol.
The system also will translate commands from pioneer to Sony and back , from pioneer to Philips and back and each combination of the three.

I would kill for a such device, but compatible with the Pioneer LD-V8000 model and so with my Galaxian Theater!  Ghost

Thank you for the update!  Smiley
May I buy one from you when you have finished it?
Do you have a good quality image file of the PAL Dragon's Lair laserdisc?

Do you have a list of hardware this is compatible with please?

I'm wondering if it would work with a SONY LDP-1500P, without any additional hardware (i.e. Laser Ace Conversion Card)

If it does, I would be very interested in this also :-)
