Open source / Java

Inside the JFTSE emulator

JFTSE recreates the server side of Fantasy Tennis. The Java project separates runnable services from the libraries and build tools they share.

Runnable services

auth-server: Signs players in and supplies channel information.
game-server: Runs lobbies, rooms and gameplay rules.
chat-server: Handles messaging and social features.
relay-server: Forwards match traffic between players.
ac-server: Handles optional anti-cheat traffic.

Shared libraries and build tools

server-core: Provides networking, packet handling and the shared server loop.
entities: Defines database models, mappings and repositories.
commons: Provides utilities, configuration helpers and scripting support.
commons-proto: Defines Protobuf messages and gRPC contracts between services.
packet-generator: Generates Java classes from packet definitions at build time.

The repository also includes container configuration in docker/ and SQL imports in scripts/. For configuration files and database tables, see the operator guide.

Model and animation tooling

FT DAT Tool

Export Fantasy Tennis DAT models and ANI animations to FBX and JSON. Import edited or newly created FBX meshes to build a DAT directly, including its sections, material assignments and render settings.

A template is optional when rebuilding an existing asset and preserving its original structure.
