The codes listed in this manual give you an idea of the kinds of effects you can create by programming your own codes to enhance game play and add to your enjoyment.
When programming your own codes, keep in mind the following guidelines:

• The easiest way to program your own codes is to make slight changes in existing codes. In the next section, there are simple tables to show you how to change the example codes in the manual to create effects you might enjoy.
• If you are making small changes to existing codes, it is best to leave the same number of letters in the code.
• You can also program codes by simply using random letters. The best results are obtained when you make up codes of 6 letters.
• Using 3 codes at a time makes it more likely to get an effect, but it's a more difficult way to program random codes, since it's harder to tell which code is making the effect happen.
• Most codes of the proper length will have some effect, but often it will be such a small change that you will not even notice any difference. You may have to try many random codes before you get an interesting effect.
• If you find a random code that has an interesting effect, then try changing it by using the programming techniques in the next section. This way, you are more likely to "home in " on a really good effect.

If a code you program interrupts the game or causes an undesired effect, just turn off the power and turn it on again, and then program different codes to play.

How to program

There are two basic methods used to program your own codes by changing existing codes.

Using method #1, you change either the first of second letter of the code. Using Method #2, you change either the first or last letter of the code.

You can also combine both methods if you wish.

Method #1 and Method #2 will work best on single codes, when the effect of the code you wish to change has numbers in it (for example, number of lives, number of bullets, number of weapons, number of seconds or minutes on the timer).

The best way to proceed is to write down the original code, look up the choices in the tables below, and then write down all the variations below the original code. This way, you can return to your Game Genie^TM with your own list of codes to try.

Reminder: If a code you program interrupts the game or causes an undesired effect, just turn off the power and turn it on again, and then program different codes to play.

Method #1

Using Method #1, you change either the first or second letter of the original code. First try changing the first letter and write down the new code. Then try changing the second. Then try changing both the first and second at the same time.

How to use the tables: Find the letter you want to change in one of the tables. Then substitute one of the otehr letters in the same table.

The farther apart two letters are in the table, the bigger the change in the effect will be. For example, in Table 1, changing A to Y will make a bigger difference than changing A to Z. In table 2, changing V to O will make a bigger difference than changing V to S.

Table 1

A

P

Z

L

G

I

T

Y

EXAMPLE: If the first or second letter of the code is P, you can change it to A, Z, L, G, I, T, or Y. Try them all!

Table 1

E

O

X

U

K

S

V

N

EXAMPLE: If the first or second letter of the code is U, you can change it to E, O, X, K, S, V or N. Try them all!

SAMPLES FOR METHOD #1: The Game Genie^TM example Code 6 for Super Mario Bros.^TM Game is A P Z L G K, which allows Mario^TM to jump higher when he's not running. Using Method #1, look up the first letter (A) in the tables. In Table 1, you find the A. One of the letters you can substitute for A is L.

Original code     A  P  Z  L  G  K          Using Table 1     L  P  Z  L  G  K

Then look up the second letter, P. You find P in Table 1 also. G is one of the letters you can substitute for P.

Original code     A  P  Z  L  G  K          Using Table 1     A  G  Z  L  G  K

Try combining these last two examples. See what you get!

The Game Genie^TM example Code 3 for Snake, Rattle 'N' Roll^TM Game is E P N N V X T T, which allows you to slow down the timer. Using Method #1, look up the first letter, E, in the tables. In table 2, you find the E. One of the letters you can substitute for E is X.

Original code     E  P  N  N  V  X  T  T          Using Table 2     X  P  N  N  V  X  T  T 

Then look up the second letter, P. You find P in table 1. Z is one of the letters you can sustitute for P.

Original code     E  P  N  N  V  X  T  T          Using Table 1     E  Z  N  N  V  X  T  T 

Try combining the last two examples. See what you get!

Method #2

In Method #2, you change either the first or last letter of the original code. First try changing the first letter. Then try changing the last. Then try changing both the first and the last at the same time.

How to use the table: Find the letter you want to change in the table and change it to the letter on its right.

EXAMPLE: If the first letter of the code is O, you can change it to P. If the last letter of the code is Y, you can change is to N.

SAMPLES FOR METHOD #2: Go back to Game Genie^TM sample code 6 for Super Mario Bros.^TM Game, A P Z L G K. Looking up the first letter, A, you see that A can be changed to E.

Original code     A  P  Z  L  G  K          Using Table 3     E  P  Z  L  G  K

Looking up the last letter, K, you see that K can be changed to G.

Original code     A  P  Z  L  G  K          Using Table 3     E  P  Z  L  G  G

Try combining these last two examples. See what you get!

And, using both methods #1 and #2, you could come up with a code like:

Original code     A  P  Z  L  G  K          Using Both Methods     Z  P  Z  L  G  G

See if you can figure out how this one was done!

Let's go back to the Game Genie example Code 3 for Snake, Rattle 'N' Roll^TM Game, E P N N V X T T. Look up the last letter, T. You find that T can be changed to V.

Original code     E  P  N  N  V  X  T  T          Using Table 3     E  P  N  N  V  X  T  V 

Remember, programming is an art that requires lots of patient, trial-and-error experimenting! The techniques will not work on all codes, bt keep trying until you discover a code that works. Of course, the methods we've described are not the only ones that might work. Feel free to invent your own programming techniques!
