"Basic local ea network emulation" is maintenance mode.
It's just very basic server responses to allow the game to boot but might not let you play.
If you want to play it properly you will most likely need a proper server.
There might be an Asphyxia plugin for it, i don't know.
I do know there is a private network that supports this game, it's where the dump originated before it was posted to 1cc.
As for me making network support for this, probably not, i don't play this game so there is no interest there for me to make a basic plugin for asphyxia like i did for chase chase jokers, or dll patches to play locally.
