Rōblox: Freedom Distribution

Adapted from the Rōblox Filtering Disabled project by Jetray, et al.

Users can host their own server instances of Rōblox using binaries from a variety of versions throughout their history.

Players can join an existing server.

Clients will automatically connect to a server of the same version.

Command Syntax

server

Game-specific options are specified in the --config_path argument, which defaults to ./GameConfig.toml. Please review each option before starting your server up.

Option	Type	Default

Misc.

Command syntaxes for studio and download also exists, but haven't been adequately documented yet.

Protocols in Use

Anyone can host a server and must leave two network ports of their choice accessible.

RCC (UDP + TCP)

RCC is an acronym for 'Rōblox Cloud Compute', which is the server-side program we use to run the Rōblox physics engine.

Host is specified by the --rcc_host or -rh option.

Port is specified by the --rcc_port or -rp option (defaults to 2005).

Webserver (HTTPS)

The webserver is responsible for facilitating player connections and loading in-game assets.

Host is optionally specified by the --webserver_host or -wh option, in case RCC is hosted elsewhere.

Port is specified by the --webserver_port or -wp option (defaults to 2006).
