Exofusion

Does anybody know the PHP game, exofusion?
It's a text-based RPG coded by Smashmethod, and now they are long gone. Exofusion has slowly disappeared, and is hardly to be found anywhere on the Internet. It just so happens to be, that I have the original version, and a new and unfinished project that smashmethod was making...

Ummm... good for you? Is this going anywhere?

I'm asking if anybody knows it.
And yes, it's going somewhere. I wanna know if it would be allowed to sell the scripts. Smashmethod has disappeared off the internet, and I saw a few other sites selling it. Wondering if it's legal or if there are any problems.
