I highly recommend not to because it can really mess up the game hence the fact of hacking, Although if you have a gameshark or action replay they will not mess the games up the cheats in those are to be helpful like super leveling up you can level up your Pokemon alot faster and such
Don't worry, just go back to the higher levels and the boulders will be there for you to push down again.
mess up
Oh, dude, let me think... oh, yeah, like, you could do some jazzing up the living room, or maybe just jam out while doing the dishes. And hey, don't forget about joking around with your family while folding laundry. Just make sure not to overdo it on the jokes, or your laundry might end up in a wrinkled mess!
It depends where you plug it in.
