Re: how do i play d2 without the disk?
Download the v1.12 patch from 'www.blizzard.com' (the one for your system, Windows or Mac).
Get your pack of CDs out and run the patch file. Copy the files 'D2music.mpq' and
'D2Xmusic.mpq' from the CD to the directory 'Program Files/Diablo 2' on your C: drive.
Follow the on-screen instructions, which will tell you which CD to put in the drive, show you a progress bar, then tell you which CD to put in next, and so on. Reboot when finished, put the CDs away, and play the game.
Seamless transition between acts -- goes right into the cinematic without that "put in the disk" stuff, and if you don't want to watch the whole show, just press Spacebar and you're into the next act right away.
