Disney's Dinosaur (PS1) BIGFILE.CAT

[BillyBnMOfficial]

I've been looking up things about the Disney's Dinosaur games and the PS1 version seems to have all data packed into a file called BIGFILE.CAT
The only thing I was able to do was view the voices of the characters in jpsxdec and I've tried looking around in Tiledggd but can't figure out the palette

If anyone has an idea of how I can extract the assets such as the textures it would be helpful
