The hack retains the core Mega Man side-scrolling loop: run, jump, charge or fire the arm cannon, defeat Robot Masters or stage enemies, collect upgrades, and learn boss patterns. Its main distinction is that it raises the challenge and changes the expected difficulty of the base campaign. Exact room order, enemy behavior, text, and available upgrades should be verified against this ROM rather than assumed from the original game.

Use the opening stage to test movement, weapon behavior, collision, and the first checkpoint before following a guide. Keep the hack’s save states separate from the clean ROM, and record the exact version in any notes. For randomizers, prototype builds, and difficulty changes, treat every stage order or damage value as version-specific.
