The author explains how sound and music synthesis, programmable characters, high resolution graphics, function key programming, animation and sprites are done in both BASIC and machine code. It also contains a full memory map of the Commodore 64 and explains how the full 64K can be used and how to correct errors in both BASIC and the KERNAL ROMs.\u003c\/p\u003e\u003cp\u003e* * *\u003c\/p\u003e\u003cp\u003eAcorn Books is proud to present its \u003cem\u003eRetro Reproductions\u003c\/em\u003e series, a collection of classic computing works from the 80s and 90s given a new lease of life in the 21\u003csup\u003est \u003c\/sup\u003ecentury.

It was designed to take 'bedroom coders' from a point where they were comfortable with the commands - and limitations - of BASIC, to having knowledge and experience of the home computer's far more powerful machine code. In addition to explaining the concepts of this more advanced language, the reader is provided with a number of example programs that not only help with learning, but are also of great practical use for both games and utilities.\u003c\/p\u003eThis book helped many a Commodore user with their first steps into the world of machine code and to this day remains an important reference for those interested in the world of retro games and programming.* * *As the original publisher \u003cem\u003eInterface Publications\u003c\/em\u003e wrote: Now, you can master machine code on the \u003cstrong\u003eCommodore 64\u003c\/strong\u003e quickly and easily. Say goodbye to jerky, slow-moving graphics in BASIC, and learn the secrets of professional, incredibly swift graphic production in machine code.You're holding the first \u003cem\u003ecomplete\u003c\/em\u003e tutorial on using assembly language on the Commodore 64. The book assumes that although you can program in BASIC, you know little or nothing of 6502\/6510 machine code. Step by simple step the book progresses through the subject, until the whole instruction set of the 6510 has been covered. A large number of example programs - which are explained in detail - help make the learning simple.In section two of the book, you'll learn about practical applications of machine code use on the Commodore 64. High resolution graphics, scrolling, raster graphics, using interrupts and adding commands to BASIC - they're all here in a form you can readily understand and apply. This section of the book contains programs which put 24 sprites on the screen at once, programs to combine both text and high-resolution images on the same screen, function key programming and one key entry of commands.Written by Mark Greenshields, highly successful author of \u003cem\u003eMastering the Commodore 64\u003c\/em\u003e, this book is your gateway into the exciting world of machine code programming on the Commodore 64.* * *Acorn Books is proud to present its \u003cem\u003eRetro Reproduction Series\u003c\/em\u003e, a collection of classic computing works from the 1980s and 90s, lovingly reproduced in the 21\u003csup\u003est\u003c\/sup\u003e century.
