Learn to Write (Retro)Videogames! new sei italiano?
Learn to Write (Retro)Videogames! new sei italiano?
Embark on a journey into the (retro)programming of three simple video games, three "easy pieces", which will help you become familiar with some basic concepts, to apply them to computers with limited resources.

The purpose of this book, therefore, is not just to illustrate a source code: instead it offers ideas for actively developing the three easy pieces.

Programming while reading.
