“If you're looking for information about how to create games for the C64 please take a look at RetroGameDev by Derek Morris. It's a brand new book which details creating two games, a space shooter and a platform game. The games were created with CBM prg Studio and so it also serves as an excellent tutorial. Please support Derek by buying this book. He's put an incredible amount of effort into it and it really shows.” (description by Arthur Jordison of CBM.prg Studio)
