I just have a few things to say. First, a question:
If I patch a newer version of BB to an older version, will my .sav file be screwed up at all, or is it perfectly safe and does my data still remain unchanged with the updated version?
Also, a congratulatory comment. These games are freaking awesome, keep up the good work.
And finally, a warning to anyone who is still at a very early point in the game:
If you think some of the leaders are hard, wait until you get to the post-game. It'll make you regret ever living. Every trainer has Pokemon above level 80.
