Welcome to Fantasy Tennis Server. This is a server emulator for the Fantasy Tennis game written in C# targetting .NET 5.0.

I am working on it in my spare time, after my full-time job so progress will be quick. The main target of this project is to sharpen my RE skills, and so while some may consider it a waste of time, I will try to document as much as possible from the client-side.

We are not there yet. Authentication is handled. You can login and create a character. Single player is not yet available.

1. install dotnet 5.0 sdk
2. start run-migration.bat
3. copy Fantasy Tennis game contents to %USERPROFILE%\ftserver\client (so that FantasyTennis.exe is in the client folder)
4. update %USERPROFILE%\ftserver\client\ServerInfo.ini to have IP_1=127.0.0.1 (local: 127.0.0.1)

1. start run-server

• Project architecture is complete (or atleast the skeleton)
• Included support for SQLite and MySQL. Currently defaults to SQLite.
• All cryptography methods have been implemented (Blowfish, Xor, Plain)

I use Ghidra to reverse engineer the client. Additionally for debugging I use x64dbg with ret-sync to synchronize Ghidra with the debugger. I will update my github repository FantasyServer.Ghidra with all the symbols I figure out. If anyone wants to pick up from where I leave off, they are welcome to it.

Public involvement is welcomed but the code must be kept to the same standard I have implemented. The server relies heavily on Dependency Injection by choice.

I started working on this because I love the game and because of the work done at https://github.com/sstokic-tgm/JFTSE and https://github.com/AnCoFT/AnCoFT. I did not want to work on JFTSE because it's java. I did not continue AnCoFT because it seems it is no longer developed and the architecture leaves a lot to be desired.
