Hmm. that may be more of a tall order than you realize.

Firstly, Welcome to GBAtemp!

Second, we need to know if you play this game with a store-bought game cartridge (which I think is the case), or with a flashcart. (R4, Acekard2i, Supercard DStwo, DSTT, etc)
If you do use a flashcart: Which one?

Simple value changes like that should be easy enough to hex edit if you or somebody else can find which files they're stored in.

Welcome to the temp

Depending on how the game was coded, changing that maybe as simple as an AR DS code, to ASM hacking. Hex editing falls around in between those 2. The possibility of you doing that solely depends on your experience in rom hacking.
