HOW TO COUNT IN HEX
Hexadecimal is the programming behind all of the games functions. Hex is what all of the GS codes are written in. There are 16 digits in the Hex language. They are as follows:

0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f

All numbers are represented using these digits. To understand Hex you must know how to translate Hex to Decimal which is what we use every day. This is how Hex is counted:

1=1
2=2
3=3
4=4
5=5
6=6
7=7
8=8
9=9
10=A
11=B
12=C
13=D
14=E
15=F
16=10
17=11
and so on......

If you do not understand this yet do not worry. I will explain further. Hex starts of like our normal way of counting up until the number 10. Then it moves on to the letters. The number 15 is letter F. F is the last letter available so it moves back to the begining with the number 1 plus the number 0. The it goes to #1 plus #1. The same way as we go from 9 to 10. In Decimal we have the numbers 1-9 and then we go back to the next number with another number.

In other words like this:
01,02,03,04,05,06,07,08,09,10,11,12,13,.......19,20,21

Now in Hex:
0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,10,11,12,......1F,20,21

I think you get the picture now. It is like we just added 6 new number to our own way of counting.

If you need to do a Hex conversion you can use the Hex calculator on this site to do them. Just type in the number in Hex and then press the DEC button to change the number to decimal. And just the opposite if you wanted to change decimal to Hex. Just press the DEC button to set it to decimal and type in your number then press the Hex button.

USING HEX IN YOUR CODES

The way you will use Hex the most in making your own codes is by changing the last four digits (the quantity digits) of the code. In the code generator it allows you to view te code in Hex and Decimal. I prefer to use the Hex view of the code. In a code the largest number you can make is FFFF in Hex which would be 65535 in decimal. You may not use that amount to much in many games. Some of the more popular choices for quantity digits are 64 in Hex which is 100 in decimal and 00 in Hex which of course is 0 in decimal. Also the digits 01 are used quite often for codes that turn things on and off. 1 means turned on and 0 means turned off. This is used mostly in in game cheats and such where you can turn it on or off and those are your only two choices.

I highly suggest that if you want to be a good code creator using the GS then learn how to use Hex first. It is your best weapon against game programming. If you get good enough you may sometimes know what values to search for to find codes without having to use Unknown Value Searches if there isn't a numerical value on the screen.
