This will be rather different to the usual project.
I uploaded packs consisting only of Touhou original game soundtracks, no remixes whatsoever. But these beatmaps are not made (or organized) by me, rather, by a whole bunch of different people, so the quality will not be consistent. If someone see a higher quality version of a particular beatmap, please reply to this topic. The songs doesn't follow any order.
Though, I do want for more Touhou soundtracks to be mapped, so everyone is allowed (okay, I don't think you need any allowance from anyone) to pitch in and create new beatmaps.
These are the songs that are in the packs:

These are the packs:
Pack 1: http://www.mediafire.com/?65nba2aazagj00l
Pack 2: http://www.mediafire.com/?vcaqai1gcfnkbx1

So I'd hope people would complete this list someday. If there's anything wrong with the links or the files in the packs etc., just reply.
If someone make a new beatmap/spotted a new one, please reply, so I can add it to the list and download it, creating new packs.
I repeat: there is no coordination whatsoever. I just compiled this pack for Touhou fanatics and hope that all the soundtracks would be mapped someday; I do not want to coordinate/organize the mapping. Of course, if someone wants to, they're welcome. For the same reason, I can't guarantee that another Touhou pack will be uploaded, until there's enough new songs.
I will compile another pack if 10 new beatmaps are born or 1 month has passed since the most recent pack, whichever comes first. As of the time this topic was made, there are only 2 packs.
