ee memory is static and always starts at 20000000

Thanks for this, even some users who can use Cheat Engline are misunderstanding meaning of the first digit of a cheat code.
Cheat Engline shows 2xxxxxxx, this 2 means a part of address not a command.
The first 8 digits of a cheat code consists 1 digit a command and 7 digits offset address from 20000000, so the first digit is a command neither a part of address nor an area of must to be "2".

Sorry if cannot understand because of my awkward English, then ignore this post.

Yeah althrough in poor english you seem to understand it correctly in cheat engine it'll be an address, but in pnach files/raw ps2 cheats because of how little memory ps2 actually has it doesn't need full 32 bits to save the address hence 1st letter is used as code type;o.
There aren't much info about different code types on pcsx2 forums, but for those interested, it can be easily found on other sites for example here. Pretty much a must have info for those who actually create cheats on their own, but also useful if you want to grab ps2 codes to add to CE cheat table to use with hotkeys, lua scripts etc..

One I can say from experience is that codes that start with a 0 and sometimes 1 in the cheat engine programs are temporary bits of info. Usually 2 are hard set in the game and always hold the same address. Such as item slots equipment slots etc. I tend to find it easier to use cheat engine then going through the converting process of pnach files. I do do it on occasion though for item hacking. Quicker that way.

The only time I ran into a 2xxxxxxxxx code that wasn't perm was in dot HACK GU with the captured chims in that area. Always resets the address each load up to a certain point in the game.

This is "emuhaste" (blue screen, the game is FF 10) one of Japanese cheat tools for multi emulators like Cheat Engine.
This tool supports raw codes, so it's one of my favorite tools.
Unfortunately most of descriptions are Japanese.

These are raw codes for this screen shot. (of course "1031A1AC 00002000" format available)

One I can say from experience is that codes that start with a 0 and sometimes 1 in the cheat engine programs are temporary bits of info. Usually 2 are hard set in the game and always hold the same address. Such as item slots equipment slots etc. I tend to find it easier to use cheat engine then going through the converting process of pnach files. I do do it on occasion though for item hacking. Quicker that way.

The only time I ran into a 2xxxxxxxxx code that wasn't perm was in dot HACK GU with the captured chims in that area. Always resets the address each load up to a certain point in the game.

When using "extended" for your cheats, the first byte is always data type, meaning that the address will start from 2******* regardless but depending on the digit, it's gonna be byte(0), short(1) or word(2), so it will patch 1, 2, or 4 bytes respectively.

If extended isn't used instead you use byte, short, or word, then the address is literal, meaning that if you try to patch an address of 03891222 for example, it will patch an address out of the game's memory, likely resulting in unexpected emulator behavior to say the least.

Most of cheat codes which provided by web sites are continuity, so overlooking what Coornio point out.

In the case of "1" command
10000000 00001234
10000002 00005678

Code:

Init:
  Address  00 01 02 03 04 05
  00000000 FF FF FF FF FF FF

10000000 00001234: ("1", short, 2 bytes writing command)
  Address  00 01 02 03 04 05
  00000000 34 12 FF FF FF FF (Address 2 and 3 are not changed)
           ^^ ^^

10000002 00005678: ("1", short, 2 bytes writing command)
  Address  00 01 02 03 04 05
  00000000 34 12 78 56 FF FF (Address 4 and 5 are not changed)
                 ^^ ^^

In the case of "2" command
20000000 00001234
20000002 00005678

Code:

Init:
  Address  00 01 02 03 04 05
  00000000 FF FF FF FF FF FF

20000000 00001234: ("2", word, 4 bytes writing command)
  Address  00 01 02 03 04 05
  00000000 34 12 00 00 FF FF (Address 2 and 3 are filled with 0 as parts of a value)
           ^^ ^^ ^^ ^^

20000002 00005678: ("2", word, 4 bytes writing command)
  Address  00 01 02 03 04 05
  00000000 34 12 78 56 00 00 (Address 4 and 5 are filled with 0 as parts of a value)
                 ^^ ^^ ^^ ^^

On the surface, almost no problems except address 4 and 5 are changed like a side-effect.
Knowing these differences is important.

Well I can say that a few games I mod I have to mod a 0 line to edit ingame values. onimusha 4 I had to use a 0 like in cheat engine to mod my souls. I think another game but I can't say for sure.
Not saying you are wrong by any means. I just learned something. Thank you.

[Scrub123]

No way, have you seen desmume's cheat interface? I'd pick a text file any day over that tedious *****.

desmumes is tedious? we are clearly looking at 2 very different things here because desmumes is straight forward and simple

and you are necroing a 6month+ thread, why?
