lukaszthegreat: true. that is a valid concern. the thing is that drm might be embodied into the core of the program and simply cannot be ever removed without reprogramming a huge chunk of it.
it is far from simple: removing few lines of the program and there is no drm.
so as long as the drm is inactive the game is drm-free.
anyhow
cracks are illegal. so even if gog is thankful they CANNOT credit the creators.
Deltantor: No, cracks are not illegal. They are perfectly legal to use as you are allowed to make all of the copies you want of games _you own_ for archival purposes as well as either use or build your own no-cd crack to use that backup.
http://www.copyright.gov/title17/92chap1.html#117 � 117. Limitations on exclusive rights: Computer programs (a) Making of Additional Copy or Adaptation by Owner of Copy. — Notwithstanding the provisions of section 106, it is
not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy
or adaptation of that computer program provided: (1) that such a new copy
or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner, or
(2) that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the computer program should cease to be rightful. In this case adaptation = modified binary aka no cd crack.
and no-cd cracks are not necessary for copy making so they do not fall under the quote you posted.
Sorry mate for busting your bubble but cracks are illegal. Any unauthorized circumvention of method used by program to ensure copyright is prohibited by law.
