Info This article is still in progress. Introduction Hopefully you’ve read the intro this series here and you know have at least a basic idea of what an emulator is about and what the roadmap is. To condense the plan into one sentence, our goal is to emulate the functionality of a game system programmatically by having an endless loop where we fetch low level instructions from ROMs (i.e. game cartridge binary dumps), execute those instructions, and repeat, updating the screen graphics as necessary.

Emulator Development Guide I was introduced to emulation at a young age by an older sibling, and I had a dream at age 5 to build a Gameboy emulator myself. I fulfilled that a few years ago, but I learned a lot along the way and I want to try and present things as I understand them in case it helps anybody. My goal is to have easy-to-follow, comprehensive guides for several of the most popular video game consoles from the 1980s, 1990s, and early 2000s.
