There is no updated version of those libraries yet, unfortunately. However, it's probably not too difficult to convert them, or write a new one yourself.
I'd do it like this: parse the tmx-file (you can probably copy that code from one of the extensions) and then draw the map directly with the "SPQuadBatch" class. If you haven't used that yet, it's somewhat similar to the "SPRenderTexture", only that it doesn't really draw objects, but simply stores their geometry. Like an endless canvas to which you can add objects!
That will be really fast and rather simple to implement.
