I just d/l a game and it is in .nrg. I don't know if i am supposed to unzip it or not or to mount it?
After finding your reguest and googling it, I came upon these results. Supposedly a .nrg file is created by nero and can be converted into an iso to burn/mount with any program. heres the link on how to convert from .nrg to .iso (its real easy!!) http://www.weethet.nl/english/cdrw_nrgtoiso.php It looks like it uses one tool to convert a .nrg file to a .iso give it a shot it should work.
