Chapter 1 Basics

This section contains some of the basic terms, concepts and ideas that will make ROM hacking and this document a bit easier to grasp. Before this starts though there are three equally important truths to know

1. Any problem as far as “what does this represent?” goes can be solved.
2. The bits you are looking at can mean anything and it is only with context you will figure out what they do in that instance.
3. The bits might represent anything but any modern, non trivial system will layer things on top of each other in a process known as abstraction. Drill down or drill up as far as you need but there will usually be a limit where going further is just for intellectual curiosity and not much more.
