I took the opportunity on my own to reupload most of the files at hanaraechan fansub community.
I'm in no way affiliated with them, but their membership is opened and non moderated so please everyone, feel free to join them.
They haven't been active since 2009, and it's a shame for new fans because all the links are dead.
All the files have been reuploaded on mega, and I've posted them in the comments of each respective entry, so the links stay in the comm and available to members only, as it's the wish of the original fansubbers.
Please as always, respect their rules of not sharing outside the community (that's why I've kept the links in their comments, just check the last page)
Concerned files: various Mago mago Arashi episodes, one VS Arashi episode and most of Tensai Shimura Doubutsuen in the Phillipines.
I repeat, I'm not in contact with any of these comm fansubbers, they don't seem active at all and part of the fandom anymore, I tried to contact them but had no reply. It's just a shame as the comm is still opened and I tried my best just to help new fans get their Arashi rainbows while still respecting the rules of the comm, and posting here was my only way to let the most people know about this ^^
EDIT: The missing TSD file has been reuploaded here thanks to bec2224 :)
EDIT 2: I've posted a complete list of the reuploads with links to the appropriated comment on my LJ so it's easier for you to find the links.
