@Hasselbalch Initially the plan was to exclude links that didn't have any downloadable content, but somewhere in between I decided they could be useful (particularly the news sites, as it could be an important resource for obscure characters that aren't here yet) and I could at least back up the webpages using the Internet Archive.

I've got mixed feelings about BGM sites as they aren't necessarily related to Mugen, but for the sake of preservation I'll back them up as well.

I'll add the tutorials as well as this http://sky.geocities.jp/haitakanomori/, thank you!
