tl;dr:Dave, a video game developer, discusses the hardest bug he’s come across and how we went about debugging it. “Among other things, I wrote the memory card code for Crash Bandicoot. For a swaggering game coder, this is like a walk in the park; I expected it would take a few days. I ended up debugging that code for 6 weeks. I did other stuff during that time, but I kept coming back to this bug - a few hours every few days. It was agonizing.”
