Building a so-called “Game Boy Macro” is a great way to salvage a Nintendo DS that has a broken hinge or top screen, as the system only needs the lower display to play Game Boy Advance

It took me a bit to figure this out, partly due to the fact of no really good explanation of it. So, I'm going to have a crack at it. Basically, I wanted to understand how keyboard matrices work. Specifically, I wanted to know why keyboard "ghosting" and "masking" happen, and how to prevent them.

All you need to know. That's a relic of the past century!
