Yes use Daphne, 100% accurate

And it can emulate the Atari euro board, hurray

Or you can mix the two worlds : using a computer to simulate the board but display the picture via a real laser disc player, hooked to your computer (I've done that for my Space Ace).
Believe me or not, but I've never seen an European Atari DL board for sale somewhere since many years... So Daphne may be your only way to go at the end.
You may use a Cinematronic board, but you would have to transform your euro DL to the US version, adding a score board (and so modify the cabinet itself

), use a different LD player... I wouldn't do that!
