    IMPORTANT
    ---------
    To calibrate the steering, do the following:
    1) Delete the .nv file
    2) Start the game.  Speed Racer will guide you through the calibration
       (the "jump button" is the same as player 1 start).
       For Final Lap R, hold down service (9) and tap test (F2).  If you do
       not get an "initializing" message followed by the input test, keep doing
       it until you do.
    3) Exit MAME and restart the game, it's now calibrated.
