I've done a lot of the legwork in reverse-engineering the ".3DM" files used by this game, but I haven't been able to quite get all the way. Attached are the files containing my research, and a few files from the game. I've got the general layout of the files, and I believe I've located the vertices, UVs, and triangles.
I hope that someone else can bring it the rest of the way, since I'm struggling to!
You can also find a copy of my notes here, specifically regarding the "HONOKA.3DM" file. There may be a few spots where I'm a little off, but it should be mostly right.
The texture files (also explained in the attached notes below) are as simple as can be. PixelDbg is sufficient for many of them.
For the rest of the files in the game, you can find the PC port on your favourite archive site.
