Quoted from Damonator:It's specific to the game #. "Charlie" is one of the names that Adam recorded so you are in luck. You can either replace the existing name callout with the Charlie callout using pinball browser or it can be done in the next software release if you know who to ask.
The name to game information used to be stored on the micro SD card, but they had to put it in the software when the insider connected stuff came out.
Here are all the name possibilities:
Damnit. There is a Matt.
