Building Your First Emulator

A NES game is a set of instructions for a processor that no longer exists. An emulator pretends to be that processor. It reads each instruction, fakes the result, and the game never knows the difference.

In this book you’ll build one from scratch: CPU, graphics, audio, input. Until it runs real games. Super Mario Bros shipped in 32 KB. Your emulator will understand every byte.

No emulation or hardware experience needed. If you can code and you’re curious about how things really work, this book is for you.

Available in Spanish and English.
