Not much to say but this is a dump of MMD stuff, you can see the name on the artists that are present in this dump in the folders, if Im not wrong some of these stopped making any content after the MMD purged that happened a while ago.
Reminder this dump just like my previous releases are backwards compatible with UBUCAv3 and UBUCAv4 , that last one is on a dire need to be seeded, stop being such a bunch of leechers guys.
