There is a TWD I play on location that currently won't allow you to set a high score.

I found someone at the arcade with a key and they let me play with the service menu. Allow high scores was set to yes. Is there another setting that needs adjusting as well?

A little more intel:
-----------------------------
The game doesn't show any default high scores during attract mode.

When in the menu, I saw the default scores for entering initials which looked normal. And I played a couple of games and did well enough to beat those defaults.

The game has a ticket dispenser hooked up.
-----------------------------

Being as I own a TWD, I'm not going to keep dropping quarters into this pin if I can't rub my initials in people's faces.

Any ideas?

The code was recently updated. Previously, it allowed high scores.

It's not the worst situation, but can be a little annoying as the machine audibly says 'ticket' a lot.

They have it set so you can't earn a free game (you can match), but you can buy a sack of tokens with your tickets.
