This ROM hack, by Sivak Drac, reimagines Mega Man 2 under the title "Adventures of Bass II, The." This modification likely involves significant restructuring of levels, enemies, and potentially the story.  The hack's alterations may range from minor tweaks to a complete overhaul, drastically changing how the game is played, and what challenges the player faces.  The original Mega Man 2 game's engine provides the foundation, but the overall experience is distinctly different from the original.
