Old Pet/Skeleton Models

[Buffet]

I've been attempting to get the old Mage/Necro Pets and Skeletons to have the old model.

I've tried the typical start up OPTIONS and unclick the tabs.

The issue is for w/e reason when I do that it's actually making me select a resolution to play with. The problem is my native desktop/screen resolution is not on the list and if I pick a different one I get a nasty error everytime the game loads because the two aren't agreeing.

Does anyone know a way to modify/delete files in my directory to make the original pet/skeleton models load?

I do appreciate any input.
Thank You!
