Nintendo DS questions

[Jeweladdict]

Questions about DS... mainly the WIFI part of it.

If we're in the same room we need only one game right? and we don't need any extra hardware?

If we're hundreds of miles apart we just need to be connected to a router and configure the router to do it right? Do we need special software? We each must have a copy of the game?

well i depends on the game... some u can play w/ only one, some u only get a few features w/ only one and yeah u only need to be in the same room to play, don't know about wifi but i know each has a diff id # so if u wanna play a specific person u put in that id
