Designing Arcade Computer Game Graphics

Over a decade ago I discovered that the PDF version of Designing Arcade Computer Game Graphics by Ari Feldman was freely available on the Internet. I remember posting links to the book on a lot of forums that I visited back then. If you download the zipped PDF from the above link you'll find the book has been distributed as 16 separate chapters, I've used Ashampoo PDF Pro 2 to combine the chapters into one complete file which you can download here. Ari Feldman also created a sprite library which is freely available from here.
