Paper Mario Thousand Year Door Game Problem

[PrincessPeach]

Hello! A few questions:

I'm about to download the paper mario 1000 yr door game, but it has "rar" at the end...does that matter even though when I open Dolphin 3.0 it says "no gc/wii isos found...click here to browse"

and also I was told told find the "path" for the game or something...what does that mean? I just want thorough steps/instructions so I can get the game up and running asap. thanks in advance

A .rar file is just a compressed file, like a .zip, but I don't know what the difference is. You will need software to extract the iso from the .rar. file.

The 'path' is just where the iso is located, in other words, the folder you put it into.
