I'm not sure if the Status code for 'Game is available to join' is correct. Using a level 1 expansion barbarian in normal difficulty, I receive 04 00 10 00 (0x00100004). Using a 77 Sorceress in act Hell, I receive 04 20 10 00 (0x00102004). Does anyone have more information on these status codes?

It tells you what type of game it is. nightmare, hell, ect...

Someone already posted the information I was looking for and I posted a link to it at the top of my post minutes after posting. It is my fault; I did not adequately search before posting.

Yay me!
