You won't be able to play Dragon's Lair with your Sony LDP-1500 if you don't built the Euro Interface...
Get all the parts for building it and read all the instructions from the links given on this topic. If you don't understand, ask someone to translate it in German.
Sorry but I close this topic until you'll make some progress on the interface. Feel free to contact me via private message.
It's all in your hands now
