I'm not saying they haven't used others work in the past, but they do have their own emulators and ROMs. They have for a long time. They are still terrible, but this just doesn't seem like a big deal to me
Edit: Also, whose lives have they ruined aside from those profiting off of distributing copyrighted material? Taking down a fan game doesn't sound life ruining
Are they? They aren't using Canoe and their own files?
