Advanced Spectrum Machine Language

This book is a collection of ready-made machine language routines that show how to archieve spectacular effects on the Spectrum. Most of the routines are aimed at creating visual displays that are at the frontiers of Spectrum's capabilities. The routines include features that have never been published before, such as: Full Screen Horizon ! Lets you change the colour of the border and screen at any point, and move this horizon at will ! Interrupts Driven Sprite Animation ! Animate objects with perfectly flicker-free movement by pixels ! High Resolution Colour ! Create an area on the Spectrum with eight times the normal Spectrum's Colour Resolution! Create images over all of the screen area, including all regions of the border !

This book is for programmers with some experience in machine language programming. All the routines are listed in labelled assembly language and the techniques and principles involved are fully explained. Other routines included in this book are PRINT, PLOTTING, DRAWNING and KEYBOARD SCAN. The routines are all of professional quality and do no involve any calls to the ROM. This means that the speed of your machine language programs can be dramatically increased using these routines.
