From the article: "I semi-recently played through the original Deus Ex, and enjoyed my time with it so much that I felt like getting into speedrunning it, which ended up with me having to create a custom speedrun timer that “injects” itself into the game in order to implement features such as auto-splitting and load time removal. This article details the rough journey I went through. It’s not super well structured, but I was sorely lacking resources such as this when I was implementing the more complicated parts of the timer, so I wanted to share my experience. This is basically a detailing of “baby’s first game hack” as none of the techniques I’ve used here are advanced, and are more basic building blocks for injecting your own stuff into another process, but resources like this article were severely lacking/hard to find in my experience, so I imagine this will still be useful to someone. If you read this entire thing then I’m afraid to say you have a fatal case of nerdism (welcome!)."
