the sixth gym is in cerulean city you have to battle misty it is very easy.
to get to the sixth gym you have to move snorlax by going to the radio tower in lavender town then talking to the man close to the elevator then going to the snorlax.
once you do use the radio thing and you know how you can choose what to listen to .
well use your pen and click the topof the circle it should say some kind of Flute make sure you can hear the sound then talk to the snorlax.next go through the cave beat brock then go to cerulean city.

Actually, there isn't really a certain order to the gyms in Kanto, so it could be Cerulean, Fuchsia, Pewter, Celadon, Saffron, or Vermillion City, or Seafoam Island.
the sixth gym is in canalave city after u can use the move surf outside battles.
Viridian gym i forgot his name the team rocket boss guy.
dude heartgold is Johto, and Kanto not SINNOH! Zigzagoon is only found in the emerald series. Im not sure what a zynx is though...
You can't. The Old Château is in the Sinnoh Region. Only Johto and Kanto are accessible in Pokemon HeartGold (which is the most amount of regions so far!)
You have to take the SS Anne to Kanto and your map will return. Another problem that could occur is there could be sound malfunctions, which usually wears off quickly.
Honestly Sinnoh is a place you are stating it as it is a pokemon? Id advise you to say how do you get TO sinnoh. But no you can not go to sinnoh nor can you go to kanto from sinnoh. But in heartgold you can go to Johto.
