I have a OSCAM server running on LInux and Diablo Wifi 2.6 cams in my TVs.
The Diablo Wifi cams are running Underworld 2.30, which is the newest version, as far as I can search the internet.
I will upload the "Underworld230.dup" file here, so other people searching for it, can find it.
In case you know of a newer version, then please upload it.
