[Asdastory Online] C# Emulator (Closed Source)

[GoldenHunter]

About the project

Since they shut down the servers for Asdastory from MaxOnSoft are closed. Me and 100% of others players really miss playing. Just to regain the feeling , I am trying to Emulator it and I don't have enough experience and knowledge.

Technical details

We need to start Emulator from scratch (Closed Source), when we finish it I'll pay for each person work with me.

Requirements / Positions

We need two C# programmer who can read the packets easily. You should have a decent amount of skill, time and the thrill to go work on it until you have it finished. We need two reverse engineer, Would be nice to have a mature programmer as well. You will get paid after you finished it and can show me proof. I am not going to get scammed. We need someone have an amazing status on Ragezone or whatever. I might consider partially paying upfront. We can discuss about the price.

Contact

If you think you're capable and actually are willing to finish this contact with me via pm for more information.

How far are you in development?
What works or what are in the works?

How far are you in development?
What works or what are in the works?

Actually, I'm a newbie in development for emulator, so I want to make my own project to make a private server and learning for me.
In the beginning, I want to make a simple emulator to understand the basic for emulating, and I want people have experience and knowledge to help me.
I hope I answered to your questions

I worked on login server and this is the result

I think now we should work on database and sniff the packets from the client and server.

 

[Yothri]

If official servers are down... Then there is no sniffing... You have to reverse engineer every single packet.

That's why because I asked for two reverse engineer in my first post, after that we need a tools for editing the client to add items and doing to change some stuff.

Is this can help me ?

I'm not sure what I'm looking at exactly, but if that's an SSL encrypted packet; then we'll be needing to get the private key or something. (Good luck brute forcing it, I don't have access to a system of that caliber)

 

[Yothri]

Mhh not entirely true.

You could also patch out ssl encryption in the client, but you still need good reverse engineers for that and it will probably take some time.



Someone haz the last client of that game?

Take this link

You must be registered to see links

Thanks, I am going to trace back WSASend and try to find if there takes place some kind of encryption...

If you find anything send it to me via PM

 

[Yothri]

It would be great if you would share the founds you have to us... I mean I downloaded from the link you gave me, but I got no information on how to start the game...

I reversed the entry point myself now, and I found out that the game uses nProtects Game Guard which is already poop because it requires heartbeat. Luckily the server is the one closing connection if there is no heartbeat so and since you are the one emulating the server you can basically poop on that. But maybe the client also closes connection if it doesnt hear the heartbeat back from the server, so you would have to patch the client already.

Furthermore, I didnt know how to start the actual client, I had to reverse that myself too...

You could have said to us that you can start the client by passing the argument "E8S4F5Q6" to the executable when starting.
Another thing I yet didnt look for is how to change the host the client connects to, that would be the next thing I am going to look for if you wont tell us here.

The client is starting for me now, but closes instantly because it cant connect to the ip which the clients gets from somewhere (idk yet from where but i'll find out).

If you want my helf lets do this in public... Then there will maybe other ppl. who see there is been working on and so on.. you know what i mean... that would be much more efficient ..
