I have tried to trade between Sapphire and Emerald (i got pokedex and 2 pokemons in both).
at first i tried trading using the wireless adapter option however when i try that it asking me to be leader or join group only in emerald however in sapphire its stuck on "please wait...".
and when i tried to cancel the wireless adapter option its all going fine till i get into the trading room, when they enter the door of the trading room the game is crushing leaving a black screen and it says"
"Link error...
check your game link cable connection, and turn the power off and on"
