Level Select:
 At the episode select screen, press Press Z,X, or Y (Z is Episode 1,
 X is Episode 2, and Y is Episode 3) then press a key between Q and O
 on the keyboard (the top row of letters.) Q is Level 1, W is level 2,
 etc. Note: Trying to warp to a registered episode in the shareware
 version will crash the game.
 
 For All Weapons and Infinite Lives:
 Before launching Raptor, type "SET S_HOST=CASTLE" at the DOS prompt.
 When you start the game you'll have infinite lives and all weapons.
 This code will expire after a few levels
 
 For Easy Money:
 Start any mission that has a weapon in it (aside from your default
 lasers.) Abort the mission then sell the weapon you were given and
 repeat the process. Keep doing this to get a lot of money!
 
 For Deathray and Health Bonus:
 While playing, press BACKSPACE to restore your health and gain a free
 deathray. You can press BACKSPACE as many times as you like for more
 deathrays. When you have enough, sell the excess for quick cash.
 
 For Birthday Mode:
 To battle cows, monkeys and other critters, set your system date to
 match the programmers' birthdays:
    March 12 Bobby Prince
    May 16 Scott Host
    August 28 Rich Fleider
    October 2 Jim Molinets
 Alternatively, turn on all the switches at the bottom of the Episode
 Select screen and darken the button. A sound will confirm this code.
