Descriptions of ChingLiu releases indicate they often produce "cracked dll" files. A DLL is a library file that software uses to perform specific functions, and replacing a legitimate DLL with a cracked one is a common method of bypassing copy protection. Unlike R2R's celebrated clean keygens, ChingLiu releases are often associated with file-sharing and torrent sites, and their patches are sometimes described as simply activating the full version without limitations rather than employing advanced emulation techniques.
