So, as many of you know, I have been working on recreating Megaman 2 using Petit Computer on the DSi/3DS, and I post my work on Youtube. So far, I haven't had any problems, but recently, I decided to set up monetization for those particular videos. Of the 4 videos I had posted so far, 3 were accepted. 1 of them was not due to "not having sufficient information regarding your commercial use rights." Now, the fact that I am recreating Megaman 2, which is a copywritten work of Capcom, may be enough to prevent me from setting up monetization (and probably should have prevented me from posting those videos in the first place) as it looks and sounds like the original, I was also looking under the Fair Use law that permits limited use of a copywritten work without requiring permission so long as it is an example of commentary, search engines, criticism, news reporting, research, teaching, library archiving and scholarship. Of these, I can only think of research and teaching to be proper examples because 1) I don't know how the original game worked, so by observation, I am recreating it from scratch and learning from it, and 2) the source code that is made is being distributed freely so others may see how it is done and learn that way. Is there anything else I need to know before I decide one way or the other on how to proceed, or do I simply have (or not have) the right under Fair Use to continue this with Youtube?
