Cheat Engine

[Silhouette]

Hi, I've been tinkering with CE for a couple months now, and I think I've got the basics down, but I've got a couple questions I'd like answered.

1) When I try to change a Single Byte value to a number larger than approximately 250, it automatically becomes a small number like say, 16. What's going on here, and how do I work with it?

2) I've tried the basic CE tutorial, but can't get the hang of Pointers, can someone help me out here, maybe with a link to a video aid or something?

3) When I restart a game, my cheated values all change location. How do I set them up so that I can save my progress with cheating?

Just simple stuff, I know. Anyways, if anyone can help out, it'd be greatly appreciated. Thanks in advance.

1:
Byte values are 8 bits
8 bits can make it contain 256 different values from 0 to 255

binary adding:
[/code]
0 = 0
1 = 1
10 = 2
11 = 3
100 = 4
101 = 5
110 = 6
111 = 7
1000 = 8
.....
11111100 =252
11111101 =253
11111110 =254
11111111 =255
100000000 =256
100000001 =257
[/code]

so, 257=100000001 but, because 1 byte is only 8 bits, only the first 8 bits are checked. So: 00000001 = 1


2:
a pointer is a 4 byte memory location containing the address of another memory location.
When something allocated memory, it has to store that memory somewhere. With pointers, you have to find out where it stored that

Check the tutorial section and the pointer part of that especially

3:
pointers or code injection

Alright, that makes a bit more sense. I spent a couple weeks last summer learning about binary, so this adds up for me. But if the first eight bits are the only ones read, then how do I set a value bigger than 255? Would I change the value-type to something other than Single Byte, or would that just mess things up?

Oh, quick question. Are pointers actually located in the code of a game, or does CE create them?
