Difficult programming and reverse-engineering challenge by Nintendo European Research & Development (NERD). In this first part I have a first look at the challenge and try different stuff. In the next video we talk about the solution.

PS: I'm not looking for a job. Just used a clickbait title based on the challenge name.
