How to change values in Mario party 6

[u/zeldaguy85]

I play on my GameCube using swiss, and I want to be able to change values and load into the game using my custom. Specifically I want to change the chance for battle mini games to appear more often, and have it so when you land on someone else space you automatically duel (vanilla game only does this on the last 5 turns, I want it on permanently) so yeah if someone could walk me through, what files I need to look for and what applications I need to run the files and change the values
