Introduction

In the previous chapters, we laid the groundwork for our Game Boy emulator by implementing the CPU’s core instruction set and a basic Memory Management Unit. However, a real system isn’t just a CPU executing instructions sequentially. Hardware components like the display, timer, and input devices need to signal the CPU when an event occurs, and the CPU needs a way to respond. This is where interrupts come in.
