While chdman is a legal, open-source tool, its usage is inextricably linked to the controversial topic of software piracy. The tool itself has no Digital Rights Management (DRM) bypassing capabilities; it merely processes data provided to it. However, the CHD format is often associated with the distribution of copyrighted arcade and console games.
