Client and server sending the following packet structures

[length] [packetID] [data]

length: The first 2 byte represent packet length like 0x04, 0x00 which 4 byte length.
packetID: second 2 byte represent packet id to handle like 0xfff0 which disconnect packetID.
data: and last packet until length was just a data.

The server will tried to load the following spt files:

LauncherSettings.spt
Channel1.spt
MusicList.spt
D007.spt
D207.spt

Explaination:

LauncherSettings.spt - Just addition of mine for storing in-game name, webport, and gameport
Channel1.spt - Just storing packet of list available room channels
MusicList.spt - Storing what server send about OJNList.dat to match the song files
D007.spt - Storing username and Character ID
D207.spt - Storing available room to join (Yeah this is singleplayer server so it must be empty)

Add new length character nickname from 5 to 12 (can't more than that since it will shorter by the game)
Fixed max buffer size in SocketServer.cs
Fixed character level changed from level 100 to level 30 after a song play in packet handler ID: 0x0fb5
