I know Pokéwalkers are wayyy out of style and SO 2009, but I lost mine pretty early on after I got Heart Gold and I still miss having it around, so I was thinking of buying one on eBay, but I really doubt there'll be any Pokéwalkers on eBay from Swedish sellers.
Would it be possible to buy a foreign Pokewalker and connect it to a Swedish localization of HG/SS?
I remember buying an American copy of SSBB when it just came out, but it didn't work on our Swedish Wii, so I'm worried the same problem would arise with this...
