A deeper-than-is-possibly-sane dive into the workings of Iridis Alpha.

Iridis Alpha is a classic of the 8-bit home computer era. An innovative, side-scrolling shoot-em-up for the Commodore 64 that was notable then and now for its technical accomplishment. This book unpacks the assembly code of the game and pores over it in minute detail. There are also lots of pretty pictures.

Work-in-progress is available for free as a Coming-Along-Nicely Edition.

If you’d like to read a hard copy instead you can get the current version from Amazon at a very reasonable price.
