Mega Man 4 (USA) (Rev A) [Hack by Insectduel v1.0] (~Megaman Showdown IV EX) (Boss Mode) is yet another ROM hack by Insectduel. Similar to previous entries, it uses Mega Man 4 (USA) Rev A as its base and is a substantial alteration of the original. The removal of "Hard" from the title suggests that while it includes a Boss Mode, the overall difficulty may be less extreme than the previous "Hard" versions.  Still, "EX" denotes it is an expanded and modified version of Insectduel's work, offering a unique experience compared to the original game.
