action replays differ from gamesharks in that action replays are newer and have less flaws, so your game will not freeze if u use it. I hope this was helpful.
Yes.
No. You can't use versions of games hacked by gamesharks in official tournaments, like Pokemon tournaments, but they're not illegal by law and there is no punishment for owning one or using one.

Cheating devices like Gameshark and Action Replay only work for one type of console. If you are playing a GBA game on the DS Lite, you can use the Game Shark for the GBA in the GBA slot on the DS.
