Running the server

[samysosaw]

Hi, I would like to run the server to learn/practice Go with a game I love and was wondering if we could get more details as to how to run this ?

Here are the steps I followed:

• Installed Docker and Docker-Compose
• Downloaded the Data.nx and added it at the root of the repo
• Downloaded the repo and ran docker compose up
• Everything started without any issues
• Downloaded the v28_noaes.exe client
• Downloaded the v28 game files and put the client inside
• Launched the client and everything worked

Here is my problem. When I try to login, I can't seem to login. I tried connecting to the valhalla-master-db-1 container with root and inserting a row in the accounts table using a query like this : insert into accounts (accountID, username, password, isLogedIn, adminLevel, isBanned, gender, dob) values (1, "user123", "test123", 0, 0, 0, 0, 1990);

The query executed fine, however I still can't log in using the provided info (user123/test123). I get the "Invalid login id" or the "wrong password" errors. The client seems to be connecting to the server because I can see the following output : 2022/05/26 14:19:25 New client from 172.X.X.X:56744

Is there anything else to get this working that I missed ?

Thank you for your help !

Are you hashing the password? The source expects an MD5 hashed password, not plaintext.

I'm not too familiar with client edits so can't help you there, but it seems like you are on this. I could use some help working on the source if you are able to.

The client offsets where discovered within a debugger which means they will be offset from the start of the executable. I suggest making the edits in an application like x32dbg

Yeah I would be interested ! Im still a beginner in Go and don't have much free time to work on it, but this looks like a good project to learn. The only issue with client edits is that most of the documentation online is for more recent versions (like v83 and up).

Maybe @Hucaru could have more info to run the game in windowed mode since theres info about that in the readme.

load the localhost in this https://x64dbg.com/ and use the offsets in the readme. The offsets won't work if you use a hex editor as I haven't normalised them. If they still don't work then use the maplestory client hook I made https://github.com/Hucaru/maplestory-client-hook

The offset for window mode is 26459C and should start with the a.o.b. C745 E4 10000000 but I suggest using a debugger to edit the application as it will take care of any padding for you. Using the difference between the value I gave here and the readme you can calculate the other offsets.

Thanks for the info ! I was able to make it windowed and remove the popup after closing. EDIT : Had to remove it from Google since it's flagged as containing a virus. If anyone needs it feel free to message me and i'll find a way to share it.
