You have to get a lot of watts on the first route and when you're taking your Pokemon out of the Pokewalker, it should say on the top screen how many watts till next route. When you get watts on the Pokewalker, don't use them all.
yea though first you have to reset pokewalker or else its not gonna be compatible when you start a new game.
you can't, you need to return the Pokemon back to the DS and go for a new stroll before you can select a new route.
Through events or getting a set amount of watts
I don't know, but I doubt it. The Yellow Forest Pokewalker Route stopped being a Wi-fi Mystery Gift on May 5, 2010.
I'm pretty sure you automaticly get all the routes back because it is also saved on the game card.
As I understand it, there is an event starting on April 1st to acquire a Pikachu that will unlock new routes in the Pokewalker.
well you should go when says conect to pokewalker and you press L+DOWN+X and its going to say you should conect with the pokewalker and it gona erase all of the data and when you conect with the pokewalker after you erase it it will register the new data and yes you will los all of the routes.
You will have to erase everything on your pokewalker if you are planning on starting a new game and using it on the new save (it should tell you how to delete pokewalker stuff in the pokewalker manual thing)
yes until you receive all of the routes you unlock by collecting watts
It's all about watts... Every time you're pokewalker records 20 steps, you get one watt. Watts can be used to help find Pokemon (-10 watts) or items (-3 watts). When you return your Pokemon from a trip, the Heartgold/ Soulsilver cartridge records the remaining watts you have on your pokewalker. Then, depending on the number of watts-in-total recorded, you get new routes that you can use the next time you put a Pokemon in the walker.
I assume you are talking about deleting a pokewalker from registration in order to register a new pokewalker. I apologize to report that you cannot do this. Each pokewalker is coded to work exclusively with their copy of Heart Gold or Soul Silver. Do not bother buying another pokewalker as they are a sham.
