Get a score of at least 50,000 and enter
WIGAN NINJA on high score table.
F7 - Completes level, but remember: you must
rescue at least 1 hostage from both of the
enemy bases to finish the game successfully!
Also, entering SPECCY MODE on the high-score
list brings on twice the amount of enemies.
Meanwhile, entering EDOM TAEHC (CHEAT MODE
backwards) gives you infinite lives, but not
infinite health, so you can still die.
