Rockman 2: The Power Fighters - Debug Mode and Secret Test

The end of 2025 is upon us! Let’s see if we can squeak in one last quickie article before the end of the year. Let’s take a brief look at the disabled debug tools inside Rockman 2: The Power Fighters (or Megaman 2, I suppose, if you’re the kind of person who pronounces NES as “ness”).
