Where is the "test" button?

Some games are forcing me to push the test button. Where is it?!;)

I guess you're talking about MAME. It depends which game/driver you're trying to play. Press [TAB] -> "Input (This game)" -> look at which buton is mapped to test (sometimes service) mode.

F2 is default...usually.
F3 reset.
