The Guardian Legend ※ Cracking Videogame Passwords S1e10

In the advent of 1990 I played NES games a lot. Knowing nothing about programming but being geekish by nature, I obsessed over cracking the password systems in those games. In this series we will study some of these systems.

This is because by trial and error, I noticed that it’s the only way to prevent Melt from making a broken H.264 encoding with horrible glitch visual artifacts and libavcodec errors in stderr when decoding. My guess it’s about H.264 level limits or something. Note 2: I derped in the video regarding the order of the ADC instructions. In the video I suggest that the ordering 23,0,1,2,…,19,20,21 does not work but 0,1,2,…,19,20,21,23 works. In fact, both are wrong. It should be 21,20,19,…,2,1,0,23. This is fixed in the downloadable source code. As annotations are no longer available (without removing the video-end screen links), I put this information here in the video description instead. #Bisqwit #Programming #ReverseEngineering #Password #NES
