It is with a heavy heart that we must announce the closure of
http://Romhacking.net . it has been wonderful 12 years.
I would like to say that RHDN's shutdown means a huge hole has been created, not just by the massive knowledge database that has been lost, but as a central for those interested in romhacking to gather.
Now, it is apparent that the database has been lost (I can't wonder another reason for them giving up). So rebuilding an empty, new site on the same address would at least fix the second problem.
