Beginning at 7:30pm EST on Friday, August 16th, Silver Hunter and a group of other Mega Man Battle Network fans are planning a speedrunning marathon of the series in order to raise $1,000 for the charity Doctors Without Borders. In addition to the six core games in the series, Silver's group will also be taking on such titles as Mega Man Battle Chip Challenge, Rockman.EXE WS, and even the fan game "Mega Man Battle Network: Chrono X." Additional runs to be performed for $500 raised towards them include a New Game + run of Mega Man Battle Network 2, a Buster-only run of the first game, Rockman.EXE N1 Battle, and a "blind race" of Mega Man Network Transmission. You can find more details about these runs here.
Finally, you can tune in for the marathon here, where they will soon be posting the account for people to donate to and a tracker.
