My friend just sold me an old 3ds xl having version 7.2 for 15 bucks to raise money to buy a new 3ds xl .I want to know what all can I do with it EASILY?. Like installing homebrew in my o3ds 10.1 was easy but browserhax is not working yet on this one yet. And if the way involves this rxtools sysnand emunand stuff then please explain what are they. I would be satisfied to get homebrew on it because I really want to get Pokémon rumble and Pokémon shuffle on it. And I would go the way that's complicated but worth it.And please be a little explenative and wordy on your answer because I'm a newbie and PLEASE don't be brief.Thanks.
