I don't think these questions goes to the Danmakufu Q&A, so I created a topic.
(1) Ripping sprites, backgrounds or music from Touhou(ZUN games), without credit is illegal, even though it isn't for commercial use?
(2) I know that there are Data Extractors on Touhou wiki for that, but are there any tutorials of how to use it?
(3) About the Extractors, am I going to lose my progress(replays/score)?
