They are really old I have figured out a lot of new stuff.
I was able to figure out the algorithm finally to this game. Still seem to have a few things wrong but I'm hoping to have some help now.
Looking at the Eve Stage 2 Long Arms file I made I found we have the correct vertex by starting at the beginning set of zeros.
Image
This is what we see in the viewer.
Image
For the faces we go just below the 80 80 80 80 's and it starts after 80 80 80 OA. But this first OA is part of the actual mesh.
Image
And we get this in the viewer.
Image
It seems like most of her mesh is there but I still see some things missing. I know i should go through each offset and find where it starts and ends. Like her head, arms, dress, ect. That would make it easier. But I still cant figure out the UV's.
Here is were they start.
Image
I was able to use a program a buddy made for me and it does work for reading them. Something about the color palette. The 80 70 is one and the 88 00 is another. That is the triangle UV's.
Image
This is the quad UV's offset start. You can tell the from the C0 70 and then 88 00. Not sure how these are read.
Image
From the program
Image
With the texture applied in into the program you can see they all line up perfectly with the image.
Image
But for some reason I cant get this UV map to show in Model Researcher. Any help on this would be appreciated. I've been working on this project for 2 years now. Each day seems to get me closer but I could really use some help at this point.
Here is a picture of the mesh in epsxe.

Well almost 3 years now. Still not able to find out the algorithm to this data. If anyone. Anyone!! Can help me.

[Update]
I used the script "ps1_disk_chunks.bms" on the original ISO and found it did change the data.

I did some digging and in the archives of the internet I found this script.
Looked promising but I cant seem to put the files in the correct spots. Or edit the script to work.
"squaresoft_cd.bms"

Programs I used/created by Leo for me. They got us close but never able to convert a file.

Here is Leo's layout of the files. I was able to get the textures by using ePSXe along with "PSXPVV"I did a tutorial on how to extract those here.

The closest I was able to get is pretty much what you see above. We were able to extract the .IMG file into .raw data we called ".PER"
After researching offsets and data we found a pattern to vertex, faces, uv1, uv2, and animation data.
Image
_____________________________________________________________________________________________
I simplified it here for what we are trying to extract here.
Image
Image
I was able to dig into the ".PER" to find this model data. I then clipped the bytes where it began and ended to get ".PEM" files. (Parasite Eve Model)
These are .raw files of vertex, face, and uv data. I used model researcher and found there is mesh in these files.
I use these as a helper too. They are the original research from Leo.

These files are old. I know. But I am using them to make new HD models. So the original topology would help along with UV's.
