MMODX NETWORK / CLIENT 0.3.0 ALPHA / PROTOCOL 7MASTER STATUS: CHECKING...
*** PUBLIC SERVER BROWSER ONLINE *** MORE THAN FOUR PLAYERS *** SYNCHRONIZED TRIALS *** MULTIPLAYER CHAO GARDENS ***

Welcome to MMODX

MMODX adds persistent dedicated-server multiplayer to Sonic Adventure DX. Players meet in hubs, chat, customize names and colors, enter synchronized action-stage trials, place individually, earn rings, and share multiplayer Chao Gardens.

This is not limited to a four-player party. Servers and rooms have configurable population caps, and the official server currently advertises room support for up to 128 players.

Controller fallback: before a trial starts, ready with E or Y from anywhere. Hold Share / View / Back / Select and press Left or Right to choose Trial A, B, or C from anywhere.

Loaded mods are explicitly declared by each host using the server configuration's Mods= field. Match that list before joining.

Installation guide

  1. Install the SADX Mod Installer. It prepares supported Steam copies and installs the Mod Loader and manager.
  2. Click Install in Mod Manager. The URI includes the name and author fields required by SA Mod Manager. If your browser blocks custom links, download the ZIP and add the archive from the manager.
  3. Enable MMODX and place it above Dreamcast Conversion and character-model packs. MMODX keeps Dreamcast Conversion enabled but takes priority for Chao content so every player uses the stock SADX Gardens.
  4. Disable the Super Sonic mod. MMODX deliberately refuses to launch while it is active because its character hooks are incompatible with multiplayer.
  5. Launch SADX. The readable server browser appears before file selection and keeps the file list locked while the selected server's completed save downloads. Choose offline to use the packaged local save instead. F4 reopens the browser later.

Official server mod catalog

The official server advertises the exact 13-entry enabled-mod order from the host profile. Search by display name, folder ID, or author. A verified GameBanana page is linked directly; otherwise the link opens a scoped GameBanana search so a similarly named mod is not falsely presented as the right one.

Also recommended: Better Input / SDL2 for modern controllers. It is a Mod Loader input feature, not one of the profile's 13 enabled mod folders.
