How to rip models from PS1 games?

[DyeffersonAz]

If PSXPrev works, you're good to go.
If it doesn't, you need to manually find and extract the models from the ROM. This is tough and there's no agreed-upon workflow, but it can be done.

My PSXPrev didn't find any model in the bin file. Where do I go from here? Trying with another file downloaded from another place will solve mt problem? Where do I start trying to extract the models from the bin file itself?
