That really depends on your standing of ports. The lower the system the better the reason to play it. While I am not saying playing Street fighter original on NES is any better then the SNES game I am just saying the more earlier the port the more official the home version is.
In my book any arcade port of any game on the saturn is visable. Even MK4 ( the one in 3d where you can walk around rooms ) would be decent on the saturn.
In short if it does the job while being diffrent at the same time then I say it is a go.
I would get the port of Saturn anyways since I know it is the underdog the same with the SNES game.
Well that would be nice but why bother on a system that overkills on power and usage. That is like all the people hunting for Marvel Vs Capcom for the X-box.
I mean all that power and I could play the same thing on my PC for free.
The Saturn ports and any other early almost direct ports is special for the reason this is the closet thing to owning the real arcade. While most of us are adults and do own cabinets

these ports allowed us to play something that was like a treat in our own homes.
