kingdom hearts 358 2 days Problem: Help please? (:

Hi
I'm new to this all Nds and Rar file and how this actually works.
I've downloaded the kingdom hearts 358 2 days european file, however it doesn't come up on the menu and i've looked for it on the media on my card and its says "RAR FILE NOT SUPPORTED" and then i tried again with a different one and it simply said something about the adapter? I'm terribly confused as to what to do.Is there anyway to fix this? Help would be much appreciated.Thanks!ps. I'm using a media adapter called EDGE.

RAR files are compressed files. You need to extract them using a program like WinRARHere is a tutorial

Also, if you do have trouble with manual patching, try finding a prepatched version.
