I'm looking for the source code of:
MetaMod:Source v1.9.0
SourceMod v1.4.8-dev

But I can not find them here:
http://hg.alliedmods.net/sourcemod-central/
and here:
http://hg.alliedmods.net/mmsource-central/

Where are they located?

This is required to compile and run the NPC extension (css server v72)

While though sources are available, other versions of the game are not supported, only the latest version directly from Steam.
