After hacking Nintendo's Super Mario Bros. edition Game & Watch, showing how to do so, and even getting other games to run on it--DOOM among them, YouTuber stacksmashing has found some of their tutorials removed from the site. Two of the user's videos involving hacking the system were taken down from YouTube via copyright claims from Nintendo. Stacksmashing decided to fire back at Nintendo, by disputing the claims, and in the meantime, uploading highly edited video where he pokes fun at the company for going after his content. He plans to re-upload the removed videos in the future by blurring out any official gameplay footage, which according to the copyright claim, is the "reason" they were taken down.
