This hack is made by Tatsu, who made the brutal yet technically impressive hack, “Rockman 2: Basic Master.” This hack is quite different, adding in new Robot Masters, new weapons, new music, and new ideas on a level not seen since Rockman 4: Minus Infinity or Rockman 2 CX. It’s that technically impressive, even featuring an 8-bit fight against Rockman 11’s Tundra Man. Version 1.1 has recently been released, which goes a long way toward mitigating the vicious difficulty of the original by making second-phase bosses reset your life bar, too, when they move to phase two. That, plus unlimited extra lives so you don’t need to use save states to train for that first crucial boss fight and several other bugfixes and quality of life changes, make this hack an easy one to recommend, difficult though it is at times. I especially applaud Tatsu’s thoughtfulness in addressing many of the issues in his hack so quickly and carefully.
