As i remember you could just disable mini games at start of the game. Or am i wrong? If it's too hard for u then just do it)
Yes, you can disable minigames at the beginnig of the game, but:
a) just at the beginning: if you started with minigames on and you repented now, the only option to disable them without tampering with the code is trhowing away your saves and replay from scratch 11 episodes with endless unskippable free roams... No, thanks...

I'd rather delete my diploma from the school database and start again my studies from kindergarten...
b) by disabling minigames you lock yourself out of some content.
So it's much better to just cheat at them.
It's as easy as modifying a single return statement in each minigame script.
