Hi Allan,
Yes, the name is right.
It is on PC and PSP but the PC version is only available in Japanese and Chinese until now.
Since it's a pretty aged game, there is no free trial for it.
I've uploaded the installer for First Chapter to Dropbox. It's DRM-free.
Here is the link: Dropbox - ed6fc
It might be illegal to do so, but I can't think of any better ways to replicate it.
Tell me when you finish the download and I'll delete the link.
After installing, just copy the attachment to "save" folder. Run the game and load the 1st save, then you may see the "White-tree" issue.
