ROM only in the table's pinmame folder
What it means
With the classic VPinMAME, this table does not start.
Why it happens
VPX 10.8.1's PinMAME plugin reads the « pinmame\roms » folder next to the table first; the classic VPinMAME only reads its own roms folder (VPX source, PinMAMEPlugin.cpp).
How Pincab Toolbox detects it
The ROM the table asks for is not in VPinMAME's roms folder, and it is in « pinmame\roms » next to the table.
