永遠のアセリア Expansion —The Spirit of Eternity Sword— (not the special edition, which has the dark route removed and replaced with all ages content)

I know the "Special edition" which contains both the original game and the expansion is around, but it has the dark route removed and replaced with all ages content...

I found the original game but not the expansion disk(s).
