Popper game whose table file is gone
What it means
These games are in Popper's menu, but their table file is gone: they do not launch.
Why it happens
PinUP Popper keeps the .vpx file name recorded at import. If the table is renamed, moved or deleted afterwards, the menu entry points at nothing.
How Pincab Toolbox detects it
The game's file name (GameFileName in the Popper database) does not exist in the tables folder, while other games of the same emulator are found there. Hidden games are ignored.
