Cracktro
The little intro a cracking crew bolted onto a pirated game — signature, greetings and chip music before the game even loaded.
When a group broke a game's copy protection, it prepended its own intro screen: a scrolling message, the crew's logo, a SID or MOD loop, and a long list of greetings to friends and rivals. On the C64 and Amiga of the mid-1980s the cracktro became the scene's billboard — the best-looking intro won prestige whether or not the game was worth cracking.
The form turned into a technical arms race: smooth scrolltext routines, raster bars and music players were sharpened in cracktros before migrating into standalone demos. Many legendary demo groups began as cracking crews, and the step from warez to the demoscene often ran straight through the intro.
