You go to sootopolis city.
Pokemon emerald gym 8 door locked.
Although the gyms are the same as ruby sapphire most of the leaders teams in emerald are different.
Wake up it and fly back to sootopolis.
Just upon entering route 128 there will be a shallow circle area with a deep patch in the centre dive down just below the shallow area and go inside the opening there will be a submarine through the opening and dive back up to the surface and you will be at the seafloor cavern.
I just did this on my emerald.
Steven and you go to cave of origin and meet with wallace.
As usual in emerald you battle your way through 8 gyms each specializing in a particular type.
You should go and find kyogre.
How do you get into the 8th gym in pokemon emerald when the door is locked answers.
Thier right but you have to go to magma hideout which is at jagged pass and aqua hideout which is near lilycove city then aqua goes to seafloor cavern which is some where pass mossdeep i forgot where battle bot archie and maxie so that groudon and kyogre can battle then go to sky pillar which is at route 131 and near pacifilog then when rayquaza is at sootoopolis they will stop fighting and.
One time it rains one time it is sunny.
When it woke up the weather will be weird.
You say rayquaza is on sky pillar.
You ll need strength surf and dive.
