Note on NES specification

Introduction

NES is Nintendo Entertainment System, a gaming console which is popular in 1980s

Hardware Overview

Since I'm reading the specification while implementing the emulator for Chip8, there will be some comparison between them.

[LINUX] Factorio Headless Server Guide

So, with credit to the Factorio wiki and cbednarski's helpful gist, I managed to eventually setup a Factorio headless server. Although, I thought the process could be nailed down/simplified to be a bit more 'tutorialised' and also to document how I got it all working for my future records.

The specific distro/version I'm using for this guide being Ubuntu Server 16.04.1 LTS. Although, that shouldn't matter, as long as your distro supports systemd (just for this guide, not a Factorio headless requirement, although most distros use it as standard now). The version of Factorio I shall be using is 0.14.20, although should work for any version of Factorio 0.14.12 and higher.

Just a note to newcomers: If there are any issues with the installation steps, people in the comments are doing a good job

Reversing Raw Binary Firmware Files in Ghidra

This brief tutorial will show you how to go about analyzing a raw binary firmware image in Ghidra.

Prep work in Binwalk

I was recently interested in reversing some older Cisco IOS images. Those images come in the form of a single binary blob, without any sort of ELF, Mach-o, or PE header to describe the binary.

While I am using Cisco IOS Images in this example, the same process should apply to other Raw Binary Firmware Images.
