extract it WinRAR...

it's my first time downloading and i know absolutely nothing blade can u elaborate on that please?

Most of the downloads here are compressed files with the file extension .zip or .rar :You can either download and install either 7zip or WinRAR...
then use it to extract the file...
the file extracted should have .nds file extension, in your case
