Seeking to extract the models from this game, and seem to have found the file in which they are located. I believe it is an archive file because multiple different filetypes found in other Sega games are present within the file (HMDL, KFMD, IZCA). I've attached several of these models in a zip.
EDIT: Upon further reading, this probably isn't an archive but the model itself. I'm going to try and do a bit more looking.
