[Unfinished][Code] NxsEmu, Emulator in C#

[DrakeFish]

Disclaimer: This is currently out of date, unfinished and not usable with the current version of the game and I am not responsible for anything you may do with this code.

It's been a while since I worked on this project as I hit a wall during development and could not get world loading to work and slowly lost interest. I wanted to wait to have a working "sandbox" before releasing this code but I figured maybe it could be useful to other people while I'm not actively working on it myself. This is an emulator which is able to go up to character creation/selection (some opcodes are probably outdated). It contains the code required to emulate all(?) of the game's network encryption.

https://bitbucket.org/drakefish/nxsemu/overview

What it currently does:

• Emulates the sts server logon and encryption used by StsConnLib. (SRP6 and RC4)
• Emulates the game's auth/realm servers and encryption. (Unknown encryption name but it currently works)
• Contains experimental packets serialisation code for readable and simple packet data.

What needs to be done for it to be a working sandbox:

• Update currently used opcodes.
• Find, code and send the right game packets for reaching the world.
• Possibly more tweaks and fixes to the packets serialization and to the bitpacker.

Note: Even though I reversed the algorithm and made my own code from it, I still don't know what algorithm the "PacketCrypt" code (link here) is based on. If anyone recognizes what it is, I would be interested in having more information about it .

Thanks for the Crypt stuff , the crypt is the stuff I needed to update my things to the latest version.

Someone still working on a Emulator?

All you need is there. Take it and update it.

This hack looks amazing!
