Um...I were uploaded Da Capo Collection back then, but they are hosted by Megaupload so all links are dead now, and I were thinking to reupload in another day :)
Just let you know, some games in Da Capo series already translated to English by MangaGamer, you can find them at the link below :D

Tell me if you are still looking for other Da Capo games, I may torrent them ^_^
