Try to find out how much memory and registers are used in the system, what architecture it is using and see if you can get hold of technical documents that describe the instruction set. When you start writing an emulator, it is important that you find as much information as possible about the system you want to emulate.

Due to small number of opcodes (35 in total for Chip 8 ) and the fact that a lot of instructions are used in more advanced CPUs, a project like this is educational (get a better understanding of how the CPU works and how machine code is executed), manageable (small number of opcodes to implement) and not too time consuming (project can be finished in a few days). Writing a Chip 8 emulator is probably the easiest emulation project you can undertake. Games written in the Chip 8 language could easily run on systems that had a Chip 8 interpreter. The Chip 8 actually never was a real system, but more like a virtual machine (VM) developed in the 70’s by Joseph Weisbecker. A benefit of this is that it won’t just allow us to run Pong, but also any other application developed for that platform. Instead, we re-create the environment with a computer program which allows us to run the original machine code of Pong. In case of an emulator, we choose not to re-implement the game Pong for our native system. In this case they simulated the looks and game behavior of Pong. Basically what happened is that people created their own implementation (clones) of the game Pong. Since not every Pong game was licensed by Atari to run on these platforms, it also meant that not every game was running the code from Atari. However, the game wasn’t just available on Atari systems, but also on rival platforms such as Amstrad, Amiga and the C64. Pong is a 2D tennis game which was developed by Atari and ran on their own hardware. Let’s take a look at the following example: Just remember that these words aren’t synonyms. Often people confuse a simulator with an emulator and vice versa.

It allows users to run software designed for this specific system (Sytem A) on a totally different computer system or architecture (System B). I think it’s important to first understand what an emulator is and isn’t.Īn emulator is a computer program that mimics the internal design and functionality of a computer system (System A). While this guide expects you to have some basic knowledge of computer systems and assumes you know a program language, it should also be an interesting read for people who are interested in emulation in general. These days however I’m more focussed on providing support to emulator projects of recent consoles such as: PCSX2 (Sony Playstation 2), Dolphin-emu (Nintendo Gamecube and Wii) and nullDC (Sega Dreamcast).

I still remember playing Super Mario 3 on the PC using a SNES/Super Famicom emulator Snes9x and a few years later completing Metal Gear Solid using Bleem! ( PSX emulator). As I didn’t own a console back in the days (only had a C64), I was pleasantly surprised when I learned that you could use an emulator to run console games on the PC. Personally I have been excited about emulators since the late 90’s. This guide is intended to give a brief introduction to the world of emulation and will also teach you how to write one yourself from scratch.
