A crack intro, also known as a cracktro, loader, or just intro, is a small introduction sequence added to cracked software. It aims to inform the user which "cracking crew" or individual cracker removed the software's copy protection and distributed the crack. [1] [2] [3]
Crack intros first appeared on Apple II computers in the late 1970s or early 1980s, [2] [4] [5] and then on ZX Spectrum, Commodore 64 and Amstrad CPC games that were distributed around the world via Bulletin Board Systems (BBSes) and floppy disk copying. [5] By 1985, when reviewing the commercially available ISEPIC cartridge which adds a custom crack intro to memory dumps of Commodore 64 software, Ahoy! wrote that such intros were "in the tradition of the true hacker". [6] Early crack intros resemble graffiti in many ways, although they invaded the private sphere and not the public space. [7] [8]
As time went on, crack intros became a medium to demonstrate the purported superiority of a cracking group. [4] Such intros grew very complex, sometimes exceeding the size [9] and complexity [10] of the software itself. Crack intros only became more sophisticated on more advanced systems such as the Amiga, Atari ST, and some IBM PC compatibles with sound cards. [5] These intros feature big, colourful effects, music, and scrollers. [11]
Cracking groups would use the intros not just to gain credit for cracking, but to advertise their BBSes, greet friends, and gain themselves recognition. [4] Messages were frequently of a vulgar nature, and on some occasions made threats of violence against software companies or the members of some rival crack-group. [4]
Crack-intro programming eventually became an art form in its own right, and people started coding intros without attaching them to a crack just to show off how well they could program. This practice evolved into the demoscene. [1]
Crack intros and other small software created by software crackers such as keygens and patches that remove protection from commercial applications often use chiptunes in the form of background music. These chiptunes are now still accessible as downloadable musicdisks or musicpacks. [12]
Software cracking is an act of removing copy protection from a software. Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software generally involves circumventing licensing and usage restrictions on commercial software by illegal methods. These methods can include modifying code directly through disassembling and bit editing, sharing stolen product keys, or developing software to generate activation keys. Examples of cracks are: applying a patch or by creating reverse-engineered serial number generators known as keygens, thus bypassing software registration and payments or converting a trial/demo version of the software into fully-functioning software without paying for it. Software cracking contributes to the rise of online piracy where pirated software is distributed to end-users through filesharing sites like BitTorrent, One click hosting (OCH), or via Usenet downloads, or by downloading bundles of the original software with cracks or keygens.
Amiga demos are demos created for the Amiga home computer.
Chiptune is a style of synthesized electronic music made using the programmable sound generator (PSG) sound chips or synthesizers in vintage arcade machines, computers and video game consoles. The term is commonly used to refer to tracker format music using extremely basic and small samples that an old computer or console could produce, as well as music that combines PSG sounds with modern musical styles. It has been described as "an interpretation of many genres" since any existing song can be arranged in a chiptune style defined more by choice of instrument and timbre than specific style elements.
Demogroups are teams of demosceners, who make computer based audio-visual works of art known as demos. Demogroups form a subculture collectively known as the demoscene.
The demoscene is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations. The purpose of a demo is to show off programming, visual art, and musical skills. Demos and other demoscene productions are shared at festivals known as demoparties, voted on by those who attend and released online.
Future Crew was a Finnish demogroup that created PC demos and software, active mostly between 1987 and 1994.
The computer art scene, or simply artscene, is the community interested and active in the creation of computer-based artwork.
The Commodore 64 (C64) demos are demonstrations of what can be done to push the limits of the Commodore 64 computer, made by programmers, musicians and artists.
FairLight (FLT) is a warez and demo group initially involved in the Commodore demoscene, and in cracking to illegally release games for free, since 1987. In addition to the C64, FairLight has also migrated towards the Amiga, Super NES and later the PC. FairLight was founded during the Easter holiday in 1987 by Strider and Black Shadow, both ex-members of West Coast Crackers (WCC). This "West Coast" was the west coast of Sweden, so FairLight was initially a Swedish group, which later became internationalized. The name was taken from the Fairlight CMI synthesizer which Strider saw Jean-Michel Jarre use on some of his records.
Tristar and Red Sector Incorporated (TRSI) is a demogroup which formed in 1990. It came about from the longest-running cooperation in scene history. RSI existed from 1985, before being joined by the "T" later on. Evolving from the Commodore 64 to the Amiga and later to PC and various game console platforms - like the PlayStation, Xbox, Nintendo - and set-ups like Arduino, Android or Blu-ray, TRSI released a number of digital productions, dedicated to experimenting in phreaking or network alteration. Its members were spread around the world and still contribute to computer scene art and code after more than 27 years of history.
The Commodore 64 amassed a large software library of nearly 10,000 commercial titles, covering most genres from games to business applications, and many others.
The Humble Guys (THG) were a cracking group for the IBM PC during the late 1980s founded by two friends known by the pseudonyms Candyman and Fabulous Furlough. The group was also noticed in the demoscene for some of their cracktros.
The Warez scene, often referred to as The Scene, is a worldwide, underground, organized network of pirate groups specializing in obtaining and illegally releasing digital media for free before their official sale date. The Scene distributes all forms of digital media, including computer games, movies, TV shows, music, and pornography. The Scene is meant to be hidden from the public, only being shared with those within the community. However, as files were commonly leaked outside the community and their popularity grew, some individuals from The Scene began leaking files and uploading them to filehosts, torrents and ed2k.
A disk magazine, colloquially known as a diskmag or diskzine, is a magazine that is distributed in electronic form to be read using computers. These had some popularity in the 1980s and 1990s as periodicals distributed on floppy disk, hence their name. The rise of the Internet in the late 1990s caused them to be superseded almost entirely by online publications, which are sometimes still called "diskmags" despite the lack of physical disks.
The demo effect is a name for computer-based real-time visual effects found in demos created by the demoscene.
Video game piracy is the unauthorized copying and distributing of video game software, and is a form of copyright infringement. It is often cited as a major problem that video game publishers face when distributing their products, due to the ease of being able to distribute games for free, via torrenting or websites offering direct download links. Right holders generally attempt to counter piracy of their products by enforcing the Digital Millennium Copyright Act, though this has never been totally successful. Digital distribution of pirated games has historically occurred on bulletin board systems (BBS), and more recently via decentralized peer-to-peer torrenting. In terms of physical distribution, Taiwan, China and Malaysia are known for major manufacturing and distribution centers for pirated game copies, while Hong Kong and Singapore are major importers.
Razor 1911 (RZR) is a warez and demogroup founded in Norway, 1986. It was the first ever such group to be initially founded exclusively as a demogroup, before moving into warez in 1987. According to the US Justice Department, Razor 1911 is the oldest software cracking group that is still active on the internet. Razor 1911 ran the diskmag 'Propaganda' until 1995.
The Exceptions were a German demo group formed in the 1980s. They were early pioneers writing demos for the Atari ST platform.
Amateur coders busy cracking the copy-protection on the latest Commodore 64 and ZX Spectrum games got into the habit of marking their work with an animated intro - or "cracktro" - inserted before the game began.
As the demo scene established its independence, chiptunes were carried out of the gaming sphere altogether to finally establish their own stand-alone format: the downloadable musicdisk.
