Who am I?
Hey everyone, I'm clearscreen / danslo. Some of you may still know me from Silkroad (primarily SREmu) emulator development. I'll get right down to business...
A couple years back, a German company released a game called Celetania (
). It is a space-based MMO that looks a whole lot like Eve Online but with a more cartoony look and a bigger focus on conquering planets and basically killing eachother. There was a monthly fee required and for what it's worth: it was a lot of fun to play. Unfortunately, the company decided for unknown reasons to discontinue the project and basically just took everything offline.
My goal is to bring this game back to life. As you may imagine, since the servers are offline, emulation is a bitch due to the absence of network traffic we can analyze. This project will be an attempt to emulate a game server purely by reverse engineering the original game client!
How will this work?
Don't let this overly ambitious idea put you off. Luckily for us, the original developers shared DLL's between server and client. Server/client specific logic is implemented in a separate DLL. Also, the game client ships with all server GSClasses ('GS' is their own stack based interpreter). This means that all we need to do is provide a couple of DLL files that grant these GSClasses some native system calls. We don't even have to code any logic! And modifying existing server logic is as easy as understanding and modifying GSClasses).
What tools / code already exists?
- a utility to decrypt celetania's media files
- a utility to decrypt celetania's gsclasses
- a utility that attempts to decompiler/translate GSClasses into readable instructions (code is ugly as hell, but I wrote it several years back)
- an initial solution that generates the required server DLL files and has stubs for functions that are called from serverlogic gsclasses - this will need the most work.
What am I looking for?
First and foremost I am gauging if there is any animo for this project. Since the original services don't exist anymore, I imagine we can have many thousands of people playing! Please let your voice be heard.
If you want to help me put in the work, I am looking for any help (in order of importance):
- Reverse engineers
- Graphical designers
