An overview of the problem light guns have with the modern television set, and a couple of ways to overcome it.

Modern Mallard Kickstarter: (unsuccessful)

It’s a big topic, and there’s a lot of little details that I had to leave out to keep it simple. For instance, there’s really a lot of possibilities for how LCD and other types of modern TVs operate, but I tried to give an overview of the most basic and common cases here. There are also more unusual light gun detection techniques for NES software (e.g. Action 53’s zapper games) that can’t really be covered by lag compensation. Feel free to discuss these in the comments.
