The journey doesn't end here.
Only partly satisfied with what I had, I took some free time on a train ride to write a wrapper for the input handling.

Now it's possible to react to user input with this simple piece of code:

```rust
let mut pad_data = ctrl::Input::new();

Button::Cross => utils::debug_print("X pressed\n"),
