Story
The game has the same story of the original, the only difference being the addition of 2 events related to the MegaMan Star Force series:

In the prologue, Harp Note was kidnapped by ClockMan.EXE (a NetNavi able to travel in time by creating warp holes) and escaped to the MegaMan Battle Network era 200 years ago. Dr. Goodall prepares a warp hole to MegaMan follow him, and warns him that he can only return to his time if he find ClockMan.

After the battle against ElecMan.EXE, ClockMan captured Roll.EXE and MegaMan.EXE searches for her in the internet, hearing a strange blue Navi was around the area. When he saw the Star Force MegaMan, MegaMan.EXE believed he was the one who captured Roll and fights against him, but later realize he's innocent and they join forces to fight against ClockMan. After defeating ClockMan, MegaMan and Harp Note return to their time, and MegaMan gives MegaMan.EXE a program that allows the player to use him and his Battle Chip.
