Guys, i have emulated the NP, authentication and the master server of fourdeltaone, tho back in 2012, so the revision is 105, we could bring it back online, only a windows (could eventually compile for linux) machine is necessary with good connection (dedicated preferably). So if anybody is interested in a project like this drop me a PM! OR if not i will eventually just realease it which works without NP, AUTH and MS (empty browser).
EDIT: Oh and by the way i just saw this was posted in BO2 section, i have emulated it for MW2!
