Before you turn on your Sony PS2, put a controller instead of dance mat in the socket.

Load up Game Mode/Arcade Mode! Once you've finally a descent song, hold down the 'x' button on your PS2 Controller.

Hold it down for a while - It should load up a cool menu called 'FREEZE ARROW ACTIVE/NON ACTIVE!'

If you make it active, then take out your controller and put back in Dance Mat.

Then in the song it will have special arrows called 'Freeze Arrows' which will come up in a straight line and you have to hold down your foot on the arrow until it stops.

Then at the end of the game it saves.
