Getting good at SNES games through DLL injection
Are you ever confronted with a problem and then think to yourself "wait a minute, I know how to code?" — that's exactly what happened there.
In this video, we keep dying in games emulated with Snes9X, and decide it's too much work to take our hands from the controller to the keyboard and back to save and load the game state.
So we decide to add a feature to Snes9X that many other emulators have, but that's not the point: mostly, we show in practice how we can modify and improve software by injecting a DLL into it, all written in Rust.

We want to hook a function, so that our code gets called... but we also want the original code to execute. How the heck does that work?
