VPinMAME ROM sound off
What it means
These games run without any ROM sound.
Why it happens
VPinMAME keeps a « sound » option per game in the registry; off, it disables game sound (PinMAME source, VPinMAMEConfig.cpp and ControllerRun.cpp).
How Pincab Toolbox detects it
The ROM's « sound » value (or else the « default » one) is 0 in VPinMAME's registry, and the table script does not set it itself.
