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.
Crack intros first appeared on Apple II computer in the late 1970s or early 1980s, 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. 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". Early crack intros resemble graffiti in many ways, although they invaded the private sphere and not the public space.
As time went on, crack intros became a medium to demonstrate the purported superiority of a cracking group. Such intros grew very complex, sometimes exceeding the size and complexity 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. These intros feature big, colourful effects, music, and scrollers.
Cracking groups would use the intros not just to gain credit for cracking, but to advertise their BBSes, greet friends, and gain themselves recognition. 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.
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.
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 or musicpacks.

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.
La scène démo, ou demoscene en anglais, est une sous-culture informatique ayant pour but la création artistique sous forme de programme, fondée sur les trois domaines que sont : la musique assistée par ordinateur, l’infographie et la programmation. Le postulat de base est de réaliser des performances technologiques/artistiques en jouant sur des astuces de programmation ou de réelles performances programmatiques. Les programmes ainsi créés sont appelés démos, les compétences employées pour produire des démos sont englobées dans le demomaking (littéralement : la création de démo).
vignette|Exemple d'un Générateur de clés EMBRACE pour Total Recorder Un générateur de clés, aussi appelé keygen (abréviation de key generator), est un programme informatique générant des numéros de série aléatoires afin d'activer un logiciel. Ce type de programme sert la plupart du temps à utiliser un logiciel ou un jeu sans acheter une clé de licence. La plupart des logiciels et jeux vidéo sont exposés, soit par des keygens, soit par des cracks, qui sont réalisés par des groupes de warez, comme Razor 1911, SKiDROW ou encore Fairlight (FLT).

The goal of this project was to study if the fabrication of glass suspended microchannel resonators was possible. Through trial and error, the process parameters were determined, starting from the ideal dose in the dry etching process. The ideal size was d ...
