"Using hacked pkm for private collections, in-game use, or battling with friends using the Union Room in local wireless or friends with whom you have exchanged Friend Codes (and are aware that your pkm are hacked) are acceptable uses. "
I have my current team in the battle box for battling my friends at school, or for use on the Battle Subway, and it'd be nice if I could edit them (or access their data such as OT) without having to take them out of the box. That said, the only way to access the battle box in-game is via the PC. The same goes for the rest of the boxes from 1-24, so I don't know why it's not accessible from Pokegen.
