Does anyone want to help a poor Arac?

Arac is tired of loading his Pokemon Leafgreen game over and over again, because his legendaries aren’t getting good enough stats for his tastes. However, Arac can only hack Hexadecimal on very basic levels, and thanks to the protection system on the advance pokemon games, the values will reset every time Arac enters a building, et ceteras.
So, what I’m asking is, can anybody tell me a persistant hacking location to change values in the advanced pokemon games such that it will not reset.
