I'm looking for a game rip of a Japanese-only game called Flower, Sun, and Rain. I don't believe an OST was released, therefore a game rip would be the only way to get my hands on it.

Here's a Wiki page for it, if you need more info.

I found these on a Goichi Suda/Grasshopper Manufacture fansite, full credits go to http://killer7.3dactionplanet.gamespy.com/.

Flower, Sun and Rain's first album:Water ~ For Relaxing Time.

Besides the main theme, F.S.R., with lyrics by Suda himself and vocals by Mia Murano, this album is mostly versions of classic works rearranged by, I assume, Masafumi Takada. Torn is credited for guitars, no idea who he is though. I added the id3 for the classic music composers names and song titles, since they were in japanese.

There is another album, Shine ~ For High Time, but I haven't found it yet.

I've compiled them and hosted them on filefactory so no one swamps the site's host. The missing numbered songs weren't on the site, and the unnumbered songs are Silver Case's OST remixes and an unused vocal theme from Flower, Sun and Rain.

I suggest the several versions of F.S.R., Remy's theme, Cuban Overture and Katharine's theme for a start, they're delightful.
