Passme 3 card and linking

--------------------------------------------------------------------------------

I have mario bro 64 on the nds. When i try to link it with other nds's, using the passme 3, if fails (also any othe game you can link fails). Is this due to the passme 3 card, Is there a way round this.

Also, how do i do a quick save.
Thanks in advance

they have to have the cart if you are gonna play multiplayer wth them WITHOT Flashing your DS, since you are using a passcard 3 so i think your DS isnt flashed, so it wont work if you dont flash.
