Unlock the harder worlds first by walking longer and collecting items and watts. Then repeat those steps until you reach a difficult world. You need a certain amount of watts to unlock a route. Route means another place. = a different world. A difficult world is like "Stormy beach", "Resort", or "Quiet Cave."You will get Shellos or Carvanna... Remember!
No. Pokewalkers, so far, are only compatible with HG/SS
No.
You can ony get pokewalkers by purchasing Pokemon heartgold or soulsilver. unless you orderd 1 off eBay but i havent checked eBay
No. There are some infrared capabilities for the cartridges but it has been stated that they are not compatible with the pokewalkers.
No, but if you have a friend with HG or SS, you can connect with him/her with your pokewalkers and your Pokemon can be playing together.
Sadly, they do not. However, there is the Global Link/Dream World now to cover for it!
Seems that the only option is to cheat.
A Pokewalker works with both the Pokemon HeartGold and SoulSilver. There is no difference between the Pokewalkers given out with both versions.
I am not sure if they will make Poke' Walkers for Black and White but, if they do they most likely the games won't be able to connect with HeartGold and SoulSilver Poke' Walkers.
1 is all
