I used to browse Toranoana's game coterie music using this link:

www.toranoana.jp/mailorder/cit/m_pagekit/event/music_all/genre/8351815b8380.html

However, it looks like they reorganized their site, and that link no longer works.  Unfortunately their site is pretty confusing (IMO), and so I can no longer figure out how to see these items.  Would anyone here know how?

Specifically, what I'm hoping to see is their full list of game music doujins.
