Will using a hacked TM ruin my legit Pokemon?

Question

I have Pokemon Soul silver and my brother has Pearl. He used an AR to hack tons of items and TM's on his game. Would it ruin the save file of my Pokemon if I traded my Pokemon over to his game, then used some TM's to learn moves?

edit: Will it ruin the legitimacy of the Pokemon learning the skill as well for online use?

Answer 1

No, it will not ruin the game, as I have done this many times before.
