There's now a wiki page
http://wiki.eqemulator.org/p?EQExtractor&frm=Main
Although I admit it's a bit sparse!
Currently working is:-
Spawn locations, pathing, doors, objects, AA's and zone data.
Pathing is more or less OK, but for big zones I think you will need to do some manual corrections when mobs walk in/out of your update range.
NOT working:-
Merchant lists, items, character inventory, everything else :P
I've tested this in POK, Korascian Warrens, Crushbone, Feerott (Dream version), Sanctum Somnium.
I'll be working on items if I get time today, if not it's the next thing on my list anyway.
Feel free to post any bugs - on github if you have an account, else here. One thing I'm not 100% sure on is the weapon graphic for non playable races (e.g. not human, elves, drakkin etc.).
And as for updates, yeah damn you real-life! On the other hand it's been a learning process for me so further updates will be quicker, assuming they don't get crazy with their struct re-ordering.
