Yep, it's a direct port.

And since the other thread got locked, I'm repeating this:

Last year, I found this for $3.99 at an EB. Turned out it was a new copy they couldn't sell as new any longer for whatever reason, so it was a nice surprise when the clerk told me that as he went to get the box and instructions.

It's definitely worth looking at, and I'd say it's at least scarce - counting the copy I got, I don't think I've seen more than four, maybe five copies in the wild.
