In this book, the author shows that machine code programming on the Commodore 64 can be simple to learn. He starts by showing how to use machine code from within Basic programs and then explores the essential techniques required for programming the 6502 processor.

The approach to games programming is tackled in three ways. He introduces techniques of games depth, writes and develops some complex machine code games and then present a collection of machine code subroutines for you to use in your own games design.

Topics such as scrolling, window projecting and sprite vectoring are typical of the type of ideas explored and explained. There is also a host of useful and essential machine code subroutines developed in this book including an assembler and an editor.
