Actually, it's still helpful to me to know if these unprotected clones run better or emulate functionality that the parent doesn't. I had no idea there were unprotected non-bootleg clones of certain games, if I did I definitely would have mentioned them in my original inquiry.
So any clones that run better than the parent are actually fair game for me. I don't want to throw those out, so any information about those will definitely help me.
