Highscores are not written Controller.stop Function - syd711/vpin-studio GitHub Wiki
For some tables, the highscores are not written when the table is launched/exited through PinUP Popper.
Browsing Nailbusters wiki, you find this page. While it mentions an other issue, the solution is the same. Tables like Twilight Zone (Bigus (MOD) 2.0) didn't have this table1_Exit routine. So you can add the below code from the wiki page and it will properly save the highscores and rom settings when you exit out of the table back into popper.
Sub Table1_Exit
Controller.stop
End Sub
Note that the VPin Studio's Table Validation now automatically detects and flags a missing Controller.stop call as a validation issue during the table scan. It doesn't fix the script for you, but it's a quick way to find every table affected by this without checking scripts manually.
