No-CD Crack Requests

[modelrailfan]

Yes, I'm a newbie, so this question has probably been asked/answered a hundred times before. I see a bunch of new no-CD cracks on the GCW homepage, and I'm wondering what gets that ball rolling? Are people requesting these and maybe even somehow providing files off their CDs (executables, I'm assuming)? As for my story, I decided the other day to copy all of my kids' programs to the harddrive, only to find that several have CD checks. Now I'm surfin' the net for Jay Jay the Jet Plane cracks, etc. I've also tried making an image for a couple with Alcohol 120%... one worked, one still doesn't. Thanks for your time.
