A game writer's utility pack which allows high speed arcade games to be written in Basic.

This is achieved by using the set of supplied machine code sprite routines to move multicoloured characters (sprites) of your own design, around the screen at high speed.

Control of the sprites' movements is by the user-written Basic program. Specific commands to the sprites are very simple.

Special routines are included to detect collision between sprites and other objects. This is an essential feature for games writing, but is found on few sprite utility packages.

Sprites are generated in mode 5 on a 9 x 16 grid and may include any of the four available clours.

A special user sprite facility allows clones of each sprite to be created, to simulate animation.

The pack contains full instructions and many demonstration programs.
