I have checked the videogames lossless thread and it doesn't seem so.
The last post there about this subject is a reupload request

(ps. what is ASTOST ?)
A chinese forum, thats got a pretty nice VGM collection and a terribly confusing sharing system based off of points (Been a member for nearly a year and still havent figured out how to get a point). Its ideal for lossless collectors because a very big section of the forum is lossless dedicated, and alot of the soundtracks listed are ones in Japanese and often don't go posted in FFshrine. I'd argue that its 3x or more effective to find what you're looking for than FFshrine and 12x more effective to find music you're not looking for as its very heavy in OSTs for datesim and other graphic novel-like games.
Like FFshrine, a great deal of the older-post links are dead because of giant falls like Megaupload or File Sonic. 115 kind of semi-fell so alot of the newer posts are using baidu, mediafire, and howfile.
