Packet 0x77 Information

I checked pvpgn bnet protocol file just now, there are 9 used statuses for SID_CREATEACCOUNT2 (SERVER_CREATEACCTREPLY2 in pvpgn)
it's only sent from D2 1.03~1.10.

And what are these 9?

0 Success
[remaining are failure codes]
1 Name blank
2 Name contains reserved characters
3 Name contains reserved words
4 Account already exists
5 (unused) - also, no mapping to SID_AUTH_ACCOUNTCREATE
6 Name too short - also mapped to SID_AUTH_ACCOUNTCREATE: no alphanumeric characters
7 (unused) Name contains adjacent punctuation
8 (unused) Name contains too much punctuation

SID_AUTH_ACCOUNTCREATE statuses are converted to SID_CREATEACCOUNT2 statuses internally by Diablo II.
Status 5 and any status not mentioned above result in a generic "account already exists" type error displayed to the user.

in C codes, NTString = None-Terminate String

Who taught you that?  I've never seen that designation.

I sometimes think of NTString as UNICODE_STRING, since that's the one that seems most native to NT...

the 3 unused statuses are seen in D2 1.10 now (at least my friend got 2 of them some times), I think they may not work in 1.09 and lower version

I checked D2 1.10 and it behaves the same for status 5 and status 4 (and any other status not mentioned above), so it's unlikely that it's used.
