E7 Header Decomposition

[Parallax]

So I've been doing a little work on the 80FB header, only two dialogue messages contained within.

Code:

0780fb 00000000 00 Do you wish to leave the Matrix?
0780fb 00000000 01 Do you wish to re-enter the Loading Area?

The packets seem only to respond to the last two bit being set to either 0 or 1; Matrix or Loading Area. Anything not zero (00) is one (10, 01, 34).
And you can put whatever you want for the first chunk after the header. The ones in the database only use the first two bits. It probably has some significance, but I can't figure it out with the one set of packets.

And the FA header - Adding hardlines to the Atlas.

Code:

0b80fa 02000000 64000000 01 Adding Hardline: "Downtown.Lamar (South Central)"
0b80fa 03000000 0d000000 01 Adding Hardline: "International.Furihata (Northeas..
0b80fa 01000000 91000000 01 Adding Hardline: "Richland.Apollyon (Southeast)"

Westview must be 00 or 04, right?
No discernable pattern to hardlines. 5c is Hampton green NW, 5d is Chelsea NC

And some were still not bringing up results for some reason. Like one that "worked" said it marked Chelsea NW, but didn't put an icon, and others didn't bring up text, so I didn't know where to look. But now I guess it would be easier, knowing which districts it's in.
