[PS2] HELP ! DRAGON QUEST 5 LZSS 3D MODELS

[UnityNoir]

Hello everyone 

I'm trying to extract the 3D models (character, object, map) of dragon quest 5 (PS2 version ).
So far, I have managed to get the game (patched English version) and extract all the files (after having unpacked the .BAT file containing the whole).
Now i find some .LZ (LZSS) files but i don't know what to do with them.
To my knowledge, there is no software allowing to open them or to convert them into an other format.
I am therefore stuck there.
It is very frustrating because all the files are there and only ask to be exploited ...
So I wanted to know if any of you, would have an idea in advance or if you thought that it will not be possible to exploit and convert the 3D models.
I can send you any file so that you can possibly see for yourself.

I searched a lot on the internet and I did not find anything allowing to recover the 3D models (and texture) from a .LZ file.

Unfortunately, I have the impression that there is no solution to recover and convert the 3D models as for the 3DS version of Dragon quest (using Ohana3DS Rebirth) for this ps2 version

Thank you in advance for your help and have a good day !!
