I just installed Diablo II and the LOD expansion on playonlinux, but I had to do it by using the original CDs. What I would like to do is use ISO images of my discs.

So I created ISO images from all 4 discs, and I tried to use AcetoneISO to mount them, but it wouldnt mount them with the correct name (it just used numbers) so I tried Gmount instead, and although I can now mount the images so they appear on my desktop, Diablo II cant see it and wont run.

What am I doing wrong? Can anyone explain how to mount an image so its available to Diablo?

AFAIK you just need to do maximum installation and then patch the game to the latest version. After that there is no need for any CD in your drive.
