This is not a book for beginners. You are expected to have a working knowledge of Z80 Assembly Language, and of course a knowledge of BASIC. But for the first time, Stuart Nicholls describes the tehniques of writing arcade games and other fast-moving programs for the Spectrum. Controlled high-resolutions movement on the screen, separate movement of foreground and background, collision detection, randomizing and counting, are just a few of the sublects dealt with in this book. Routines for sound include lasers, white noise (for explosions etc) and music.
