@vinlind I've only ever dipped my toe into reverse engineering games, cause it takes more than the five minutes my brain allots to any one task uwu. however the five minutes I was given for this task let me use my knowledge to dig up this site that seems legit, at least the random sampling of articles I read and the intro to their intro to reverse engineering passed muster.

Used to watch some youtubers too I'll let you know if I recall them.
