The patch only fixes a missing sound file problem for a drum in the go-go dancer's dream world (the Persian one).
This might help:
"The object here is to throw the correct dart from each of the six booths (after a correct dart is thrown, the corresponding tap handle is pulled down). Throw one incorrect dart at then board, and the other darts already in the board simply disappear, requiring you to start again. If we number the booth closest to the dart-board as 1, and the one farthest from the board as 6, and if we number the darts 1 through 6 running top to bottom in the dart box, we get the following matches:
Booth 1 - Dart 3
Booth 2 - Dart 1
Booth 3 - Dart 5
Booth 4 - Dart 6
Booth 5 - Dart 2
Booth 6 - Dart 4
Once finished, all six tap handles are pulled, and the fireplace spins to reveal a passageway into the back alley."
