If you guys have some time, you still can have a look at this old database. (I think most of them are offline, but just in case.)

OolongV's bookmarks can still be useful

I wrote about it not too long ago in the code archive:

Part 2: OolongV's MUGEN Boomarks (included in tutorials download) - A history of MUGEN Websites

With the internet archive, and OolongV's MUGEN Bookmarks you can browse through the history of MUGEN websites throughout the years.
For those that weren't around, in MUGENs best days there were 100s of different mugen websites, forums, and communities. Thanks to OolongV for his bookmarks. Click on a link you want to see their old site. If the link doesn't work you use the top bar "Internet Archive Wayback Machine" and choose another date or year until you find a link that works. Some websites were never archived, but most of them work. 100s of old mugen sites. Most downloads from an archived site don't work, but try and you may be surprised.

Fantastic and complete mugen archieve

FYI, Japanese geocities server is going to be closed soon so if anyone feels concerned about this, it's time to download from geocities before those MUGEN contents disappear forever. Also, I really hope that our hosting sections can get as much MUGEN contents on geocities as much as possible or we could potentially lose a lot of creations.
