Re: D2 classic without a cd
When you connect to Battle.net with the Diablo you downloaded from Blizzard, it will probably update your Diablo to version 1.13
This should allow you to play without the CD inserted, provided you did a full install and let the update copy the file(s) it needs from the third CD of your install.
I'm glad you didn't find anything that cracks Google, because I'm rather fond of Google and prefer it uncracked. Also, downloading programs from unofficial sites leaves your computer open to a world of hurtcraft. The programs are more likely to destroy everything on your computer then do what you might expect of them.
As you may understand from the text at the top of every page on this forum, mentioning/using/linking to things like cracks, hacks or cheats for Diablo 1, 2 or 3 will get you banned from this site.
