I'm not sure I can do this
but give me the files, although I do not promise anything..
Okay...
I've compiled the files that don't seem to work (or work correctly) in Ohana3DS and put them in a .zip folder.
DQ VII
1. The .bcmdl.lz file for p0001_j00 almost works correctly, but, the facial textures are missing (though, if extracted from .lz in SPICA, the model has all it's textures, but, loses the textures when exported).
2. The .pack.lz for p0001_j00 doesn't work at all in both Ohana3DS and SPICA.
3. The last two .pack.lz files are ingame maps, but, no preview of the model file whatsoever shows up, just the listed models in the .pack.lz file (see the below picture).
DQ VIII
1. These .xbb files really peak my curiosity and I think they contain the extra textures such as facial expressions, unfortunately, I cannot open the file in Ohana3DS or SPICA.
2. x05i12_null (which is a map), doesn't show anything when opened up and I believe it could be an iconic ingame location, as I have looked for that location in the other files and haven't found it yet.
