Animal Crossing rar extraction unsuccessful

Hi there my name is David and I've been having some problems opening up a ROM found on this site. I found the ROM at http://www.emuparadise.me/Nintendo_G...66075-download and was able to download the .RAR file. After that I used 7-zip to extract the file giving me only .NFO, .ZIP and .SFV extensions and no .ISO (which is what I believe I should have been expecting). After opening the .ZIP extension file I found a .GCM and .DIZ extension files.

I am using dolphin 4.0-6266 emulator. I am running Windows 8.1 with Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz with a 64-bit operating system. I believe my graphics card is a GeForce GT 635M (found on NVIDEA system information). I currently live in Canada (North America).

I was hoping that someone out there could give me a step by step guide on how to successfully run the animal crossing ROM from the bottom up.

Thank you very much for taking the time to read this and hopefully someone can help me out!

The gcm file is an iso it does not need to be renamed unless you are burning it as dolphin can read gcm files just fine

iso is a general term for a disc image rather than a file type, something that does get a lot of people confused

You need to extract the zip file.

Thank you zorlon and swmas for your quick replies, should have extracted the zip file as soon as I saw it instead of just opening it in my file explorer... Anyway this was all I needed so thank you and have an awesome day!
