Always wanted to create those colorful intros yourself? The new released Webdeff editor can help you and comes with many basic scripts to get started. 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. Additional performance was achieved by utilizing several co-processors in parallel with the 68000. These co-processors include, Copper and Blitter . To achieve the best speed most demos disabled the operating system and addressed the hardware directly. Smaller demos are often known as intros. They are typically limited to between 4 and 64KB in size. Intros were originally used as tags by cracking groups on computer games and other software. The purpose of the intro was to advertise cracking and distribution skill of a particular group. Later it developed into a stand-alone art form. Many demo and intro groups disassociated themselves from the cracking and copying scene, although the same people could still be involved in it. For more information please click this link.
