Well almost 3 years now. Still not able to find out the algorithm to this data. If anyone. Anyone!! Can help me.
I used the script "ps1_disk_chunks.bms" on the original ISO and found it did change the data.
Original Unchunked Offest
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.

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. https://www.youtube.com/watch?v=AikdXGBN_-k
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.
I simplified it here for what we are trying to extract here.
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.
