These are all bosses or until where.
Btw, in the first fight against lemmy, it already start weakened.
Also, I think you should look the scs1and2 beastiary to compare, for example, the metal horse is called iron horse in 2.
I don't know if you already know that, but I tried patch in 2 different patchers and:
With "Rom Patcher" (android app) ritch calls V.E. as sister,
But in "NUPS" (Windows) it calls her nee-chan.
I tought it would be interesting for u to look it, and yes, it was the exact same rom I used
