I am no master at these but I would like to share my CT file for the minigames
Update 2:
Rope Climb - Always win when activated (just activate then play the mini game)
Whack-A-Mole - Always hit moles when activated (just activate and press any of the six button it will always hit the mole but you still have to watch out for the penalty mole so you don't hit it

)
Chinchirorin(Dice Game) - Always throw Three of a Kind (No activation needed, play the mini game and when it's your turn to roll just change the Value to six (6) to win with Three of a Kind)
Chinchirorin(Dice Game) - Activate to always win (no need to set value, Shilo will always throw Three 1's)
Fishing - Fish Catch Modifier (choose what fish to catch), Easy Catch(no more struggle catching don't have to press anything once activated)
It's not perfect but it gets the job done.
Let me know if it works for you too
