X = Difficulty
0 = Easy
1 = Medium
2 = Hard

#Write over CPU difficulty setting byte in memory
li r0, 2 #Hard used for assembling, adjust this to what you want
stw r0, 0x1C (r3)

#Original Instruction of Hook Address
li r3, 20

/*NOTE: I did 1 test on GP, VS, Battle, and Coins. The parent func seems to be the only one to call the responsible child func (one instruction above hook addr), however this could be wrong. If code doesn't work because this parent func isn't always used to call child func, then we need to edit the child func. Code for this in PAL is...

I have a question
what does stw r0, 0x1c(r3) do?
