What on earth is the differance between AR codes and codebreaker codes?

[Oichi]

Also what are shark codes?Forgive my ignorance but i seriously have no clue.

They originate from different cheat devices.

In the end you'll want to convert all the codes to raw unencrypted codes for pnach use though. (use a tool such as omniconvert to do this.)

So actually all these codes represent exactly the same: It is all about memory modification which allows you to break the laws of the game aka cheating. They are just encrypted to different formats which was probably some copyright protection.
