Cheat mode: Cheat codes are enabled at the copyright screen that
appears after the game is reset. They are entered by pressing
A to created a letter in Morse code. A dot is created
by tapping A. A dash is created by holding A briefly
before releasing it. The sound of Morse code will confirm correct
code entry. Up to two codes can be enabled by starting the second
code after the sound of the first code being confirmed is heard.
However you are limited to activating the "C" or "D"
codes first, then only the "R", "L" or "X"
codes second.
