Just downloaded the Shareware version

So I found a Tungston E2 at goodwill for $5, decided why not and picked it up. Found this game and downloaded it to a SD card and put it in the E2.
The game is pretty freaking sweet so far!
Just wondering if I have to get my E2 setup to internet or does the registration work with it offline?
