Rockman 4 Minus Infinity isn’t just the best romhack ever made. It’s superior to the NES Mega Man games in every way. Puresabe just released v1.00 a few days ago, and what it does to Mega Man 4 is ridiculous. This features redesigned stages, bosses, and weapons, tons of new music, autosaves, 8-way scrolling, difficulty options, a time attack, and multiple boss rush modes, and that’s just the start. JDetan and I call this the real Mega Man 4, and the other one just a beta.
