I wrote a book called "Amiga Assembly Game Programming".
This book is dedicated to retro-computing enthusiasts and those who want to learn how to program a video game for a historic computer such as the Commodore Amiga. Programming video games for this computer is done by interfacing directly with the hardware, without using the Operating System. The book will guide you step by step in the creation of a side-scrolling shoot'em up video game, using Assembly language. You will learn how to use modern development and debugging tools and you can use the emulator to run Amiga programs. If you do not know Assembly language, the book offers an entire chapter dedicated to this language. At the end you will be a real guru of Amiga hardware programming and you will be able to create other video games or demos!
The book is already available on Amazon:
