An Intro on the Amiga is a size-restricted executable demonstration, typically limited to 4 kilobytes (4K) or 64 kilobytes (64K), that showcases real-time graphics, sound, and programming skill within severe constraints. These productions utilize advanced size-coding techniques in 68000 assembly language to generate procedural graphics, synthesize music via the Paula chip, and create complex effects that far exceed their modest file sizes. Intros represent a cornerstone of the demoscene culture on the Amiga, where coders exploit hardware tricks and compression algorithms to maximize visual impact, often serving as standalone art pieces or as cracktros preceding pirated software.
