Answer my little questions
-When you play Wi-Fi do you have you're battles record? (example:10 wins - 0 lose - 0 draw) ? You can find it on your trainer card.
-Can you exchange Pokemon's from 2 game with 1 DS ? It'd be unnecessarily difficult, so I'd just suggest asking someone from here. I'm sure we'd all be willing to help you.
-Can you report someone if he cheated on the battle restrictions
Mhm, just say if he hacked or what exactly the offense was.
-Can you change you're sprite so peoples can see you as for example a Pokemon breeder(sprite)
In the Union Room and on Wi-Fi. Talk to the chick in the Oreburgh PokéCenter.
-Off topic:where is the cheapest place to buy a DS? Any retailer is going to have around the same price for new and used DSes, but try eBay.
