Mega Man 4 Voyage is an extensive hack of the original NES game, featuring changes to level design, music, graphics, weapons, enemies, and bosses. The basic "run, jump and shoot" Mega Man mechanic remains intact, and the hack's authors write that it "should be suitable for veterans and casual players alike."
In this run, Baddap1 completes the game as quickly as possible by using the new Speed Boost item, most of the weapons, and general strategies such as luck manipulation and time-saving damage.
We also have runs of Rockman 4 Burst Chaser × Air Sliding and Rockman 4 Minus Infinity.
