To enter this cheat mode, you must be able to beat the current
 continent's high score table.  Africa is the easiest.  After making
 a high score, enter '750J' for your name.  It should change to "...."
 if it works.  Hold down Control, Left Alternate, Z, and T as the
 credits screen changes to the options screen.  Let go of the T key
 and the cheat mode will be on.  Enter new coefficients for the road
 turns using the keypad.  The initial settings are 60 for an outer
 turn and 45 for an inner.  You also gain a machine gun.  Use it with
 the amiga key.  It can be used to destroy other bikes or  roadside
 obstacles.
