First, you aren't the world record holder, sorry. You are 2nd with the current v1.00.92
Second, speedrun.com is old, outdated, and isn't a real leaderboard for the game. Mega Man Leaderboards is where the leaderboards for the game will be.
Third, its already been decided that Hadouken will NOT be a single button. You just need to increase your skill level.
Fourth, if you continue to spam this "request" then you will be banned from commenting further.
