and disk capacity, the Commodore 64 was a popular platform for BBS hosting. Some of the most popular installations included the highly optimized and fast Blue Board program, and the Color64 BBS System, which allowed the use of color PETSCII graphics. Many BBS sysops used high-capacity floppy drives like the SFD-1001 or hard drives such as the Lt. Kernal. Software cracking The C64 software market had widespread problems with copyright infringement. There were many kinds of copy protection systems, employed on both cassette and floppy disk, to prevent the unauthorized copying of commercial Commodore 64 software. Practically all of them were worked around or defeated by crackers and warez groups. The popularity of this activity has been attributed to the large Commodore 64 user base. Many BBSs offered cracked commercial software, sometimes requiring special access and usually requiring users to maintain an upload/download ratio. A large number of warez groups existed, including Fairlight, which continued to exist more than a decade after the C64's demise. Some members of these groups turned to telephone phreaking and credit card or calling card fraud to make long-distance calls, either to download new titles not yet available locally or to upload newly cracked titles released by the group. Not all Commodore 64 users had modems, however. For these people, many warez group "swappers" maintained contacts throughout the world. These contacts would usually mass-mail cracked floppy disks through the postal service. Also, sneakernets existed at schools and businesses all over the world, as friends and colleagues would trade (and usually later copy) their software collections. At a time before the Internet was widespread, this was the only way for many users to amass huge software libraries. Also, and particularly in Europe, groups of people would hold copy-parties explicitly to copy software, usually irrespective of software licence. Several popular utilities were sold that contained custom routines to defeat most copy-protection schemes in commercial software. (Fast Hack'em—probably the most popular example—was itself widely redistributed.) Pirates Toolbox was another popular set of tools for copying disks and removing copy protection. Tapes could be copied with special software, but often it was simply done by dubbing the cassette in a dual-deck tape recorder or by relying on an Action Replay cartridge to freeze the program in memory and save to cassette. Cracked games could often be copied manually without any special tools. In Europe, some hardware devices, colloquially known
