Super Hang-On

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.
