There are two ways to get to Saffron City. One way is to have 2 Fire Red/Leaf Green, but 1 of them have to be able to buy fresh water. You trade over the fresh water to the other Fire Red/Leaf Green and give the fresh water to the guard. Give it to any guard. Another way is to Get to Lavender Town, located east of Saffron City, then take the underground route to Celadon. (You have to go through Rock Tunnel to get to Lavender Town) When you get to Celadon City, go past the 3 little houses beside the Pokemon Center, and into the big hotel, the sign will say "Celadon Mansion". Go into the mansion and talk to the old lady in the 1st floor, she will be next to a Meowth. She'll give you "tea" and give the tea to the guard. Then they'll allow you to get to Saffron City.
