Aside from an Emulator, how does one play III or IV?

I don't think you can, at least on the modern platforms.
I had III on the PSP and IV on the PSVita/PS3, but those are already old and gone platforms, too.

I'm at a bit of a loss as to who the top two are supposed to be. The guardsmen who escorted Nina at the beginning?
