Sorry. It's complicated with The different keyboard layouts. Batch probably uses a french keyboard, you an italian and kiwi maybe an us one.
After clicking on the
DMD, The key you need to press is The tilde key: ~
In my german keyboard i think it was altGr+"+". Or The key left of the number one. Depends if vpinmame ignores the selected Keyboard Layout.
On my PC the menu you're talking about "INPUT-GENERAL / INPUT-THIS GAME / DIP SWITCHES..."
appears when I press the key with 2 arrows on the left of the key "A"
which is under the key with the little "2" on the left of the key with "1" over "&"
2 arrows? You mean TAB? That's left of q.
Left of a? That's capslock.
Little 2? (Squared). That's on the 2 key.
& with a 1 over it?
You have a Very strange keyboard layout.
