Sonic Adventure 2Archipelago randomizer mod

Compatibility notes

• Use the matching 2.4.6 mod ZIP and sa2b.apworld. Its World metadata requires Archipelago 0.6.3 or newer. Install SA Mod Manager and .NET Desktop Runtime 8, launch the unmodified game once, then enable the mod. The supplied troubleshooting text still mentions APCpp.dll; that instruction predates this release.
• The Steam PC game is required. Battle DLC is needed only when Chao Karate checks are enabled. Optional SADX music requires your own Sonic Adventure DX installation and a local copy of its music files.
• Linux and Steam Deck instructions run the Windows game and manager through Proton. Launch the game from Steam rather than the manager’s Save & Play button. This review does not validate a particular Proton/game/loader combination.
• Create a fresh save for a new multiworld and resume the same slot. Keep backups of both main and Chao saves: main-save redirection is enabled, while Chao-save redirection is disabled. Keep IgnoreFileSafety off; save matching exists but is not a complete pre-synchronisation barrier.
• The room password is stored in mod configuration. Keep it private and avoid reusing sensitive credentials. The connection library can fall back to unencrypted transport after initial TLS failures.
• Reconnection restores server checks and polls saved local flags. Queued junk and trap effects are not durable, and final victory has no persistent resend queue. After an interruption, check received progression and server completion status before continuing.
• The setup guide recommends a frame-rate cap for timing/display problems and identifies SA2 Input Controls conflicts with some minigames. Expert logic assumes advanced techniques; extra Chao, collection and minigame options can substantially extend a seed.
• The package contains music and graphical resources. Their presence in source was checked, but a complete resource-permission and dependency-notice inventory was not established. This describes the available evidence, not a finding of unauthorised use.
