Put the Firered cartridge into the GBA slot of your DS (this cannot be done if you own a DSi, DSi XL, or a 3DS). Then put in your Soulsilver and turn in on. On the screen that you select your save file, choose mystery gift, and your wifi settings, there should be an option that says Migrate from Firered. The Pokemon cannot know and HM moves (like Fly or Surf). Choose six Pokemon to migrate and your all set to catch them. Fly to Fuchsia City in the Kanto reigon and head to where the Safari Zone was in Firered. There should know be a building where you can re-catch the Pokemon you migrated from Firered.
You should get a Duskull and evolve it [it evolves at lvl 37 to Dusklops] then get a Shuppet the evolve that [it evolves at lvl 37 too] then teach it a ghost type move or dark type move, then train and that is how to beat the 7th gym leader in Pokemon Emerald. Good luck!!
Check the trash cans in the gym you should eventually find a switch now check the can next to the one where you found the switch this can be the one above/below you or to the left/right. Once you find the 2nd switch you can challenge the leader.
I'm not sure about leaf green but on firered it's in the basement of the poke mansion. I'm thinking it should be the same since firered and leaf green are so similar.
Go to Celadon City, and go into one of the big buildings. In one of them, there should be a women with a lot of Pokemon with her, talk to her, and she should give you the drink.
you should have a lvl 50 water type
The Unknown are in the seventh island. Go to the southern part of the island and surf. You will find some radomn caves in which the unknown should be in.
(Excluding legendary pokemon) It should be dragonite...
pokeballs... which should be at the mart..

Charizard is the best choice
You should definitely get Pokémon Emerald.
Flying and or fire types
20 bucks at the most

you put FireRed at the bottom of your DS. Then if you have Pokemon Diamond,Pearl or Platnum insert those into your DS and where it shows where your saved game go down a little bit and it should say "Migrate From FireRed."
Give a Firestone to your Vulpix and it should evolve into one.
