Problem Generating Monsters MR3

Monster Rancher 3 problem

So, I've tried multiple ways to generate monsters but they all keep failing.

First, I tried using ps2 roms but iso files, which make up the majority, keep confusing the application, asking if I want to make a monster from the Monster Rancher 3 disc. Of course, that only generates one kind of monster: a mochi.

I tried burning fake cds using random text. I get mochi.

I tried using ps1 roms/cds, it immediately exits, yelling about how it isn't designed to play PS1 games.

I tried using a CD coming from a pc game. I get mochi.

The only reason I have any hope at all is that I managed to get a Hengar from one of the PS2 files that was a bin file.

Any ideas?

I think it somehow reads from a physical part of the disc.
tried using a real PS2 game in your DVD reader instead of iso ?

Alright, tried that, it couldn't recognize them as being distinct from the MR3 disc either.

You can modify the build to make that work, but there has been no fixes for this thus far.
