One of the old domains / sister site to XboxHacker was XboxDeveloper.NET (in the timeframe of the original Xbox).
Over time, I let the domain lapse as the need for the site fell off, in addition to upkeep issues with the server and data and general lack of time.
Out of curiosity, I was checking what happened with the domain (used to be held by ad squatters for a while). On whois, looks like the owner is now Microsoft.
