Editing Amiga demos (section)

==Demo software==
Most demos were written in [[68000]] [[assembly language]], although a few were written in C and other languages. To utilize full hardware performance, Amiga demos were optimized and written entirely for one purpose in assembly (avoiding generic and portable code). Additional performance was achieved by utilizing several coprocessors, including a [[blitter]], in parallel with the 68000. Most demos bypassed the operating system and addressed the hardware directly.

First bigger demos were released in 1987, one of them was "Tech Tech" by Sodan & Magician 42, it was released in November 1987 and is considered a classic by many.{{who|date=June 2021}}

Eric Schwartz produced a series of animated demos that ran with MoviePlayer, an animation software package similar to [[Toon Boom]]. The animated demos drew heavily on the whimsy and graphic style of comic strips.

Red Sector Incorporated produced a piece of software called the RSI Demomaker, which allowed users to script their own demos, replete with scrolltext, vectorballs, plasma screens, etc.

Full demos range from under 128 KB to several megabytes. There have been several thousand demos produced in many countries. Some active demo countries were [[Denmark]], [[Finland]], [[Germany]], [[Italy]], the [[Netherlands]], [[Norway]], [[Sweden]], [[United Kingdom|UK]], [[Poland]] and others.
