For all four digit codes, imagine an "01 xx" at the beginning. For example, the code for the Pok�mon's Status is actually 01 xx 6FD1. In some cases there are two addresses because the number is too large to be stored in one byte. Add an "01 xx" before each address. For example, the current HP is 01 xx 6CD1 and 01 xx 6DD1. If it says "number" at the end, substitute the number that you want for xx. If it is a code, click on the link to see the data for xx.
Unless otherwise specified, numbers are hexadecimal.
Find out about hexadecimal numbers and bitmask codes here. Bitmask codes are tedious and only necessary if you want to give yourself, for example, one or two badges and not all of them.

Please note:
Change EXP and Level at the same time, so the Pok�mon is at the correct level for that amount of EXP.
If a Pok�mon has only one Type, both addresses contain this Type. This caught me out for a long time when I tried to hack for it.
You can't see the Type change.
The actual stats of the Pok�mon reset when the Pok�mon goes up a level or when you put it in the PC. You can change it reasonably stably by changing the second species and putting the Pok�mon in the PC. Almost everything resets if the Pok�mon evolves.
Something strange can happen to the Pok�mon if you change either of its species to one with a different Level Up formula, though you can sometimes get away with changing the second species.
With the letter codes you can get a far greater variety of characters than if you play by the rules. Pok�mon with bizarre names.... � If you enter numbers less than 80 you get graphics characters from the game. These sometimes change with the area you are in.
You don't get Pok�dex data for modifying an existing Pok�mon.
