Give it time. I estimate between 5 and 10 years before the compatibility list is respectable enough. That is roughly the same estimate I give for other relatively recent console emulators. In fact, the exception to this would be to buy the actual console and then mod it to run whatever you want. It is beyond my expertise so if I were to go this route I would probably pay someone to set one up, I figure the cost will cancel out if you intend to flesh out your library.
