Volume controls for Scorpion 2
In order to regain sound on BFM Scorpion 2/adder games, it is necessary to reset the volume control to an acceptable level.Firstly, you must open the door (F1), then press the test switch (Y).
Depending on your game, you then need to use various buttons to actually move through the menu.
'Test Step' moves through the tests, you will need to press it until you get to 'SET VOLUME', before pressing 'Test Select'.
Then use 'Up' and 'Down' to select the required volume level.
To store the level, press and hold 'Test Step' before pressing 'Test Select', and then release both.
Although I have used these labels for simplicity, the actual games use different names for these buttons, as shown on the 'lamp panel' at the bottom of the game screen. Use those as a guide.
