Hello,
unfortunately it seems that the soundtrack for this underrated but wonderful game cannot be found anywhere.

There is a thread on this forum about Infinite Undiscovery (http://forums.ffshrine.org/f72/%5Beac%5D%5Bsqex-10122~4%5D-infinite-undiscovery-original-soundtrack-133569/) but the links are dead.

Do you know where can I find this nice soundtrack signed by Motoi Sakuraba?

Thanks a lot!
