Sonic Adventure DX
Sonic Adventure DX + Adventure Mods
Not a port: the Steam release of Sonic Adventure DX, modded with Adventure Mods' DX Enhanced preset and launched through Steam under Proton.
¶ What this is
The Windows Steam version with SA Mod Manager in place of Sonic Adventure DX.exe (the
original is kept as a .bak). The manager loads the DX Enhanced preset, 28 mods, then starts
the game. All game data belongs to Steam; nothing ships with the launcher.
¶ Requirements
- Ownership: Sonic Adventure DX on Steam.
- Proton 10.0 forced for this title (GE-Proton10-34 also works). SA Mod Manager does not start on Proton 11, Experimental or Hotfix builds.
- .NET Desktop 8 and 10 inside the game's Proton prefix.
- AdventureMods flatpak 1.2.2 for setup and restore.
¶ Launch
Start it through Steam, so Proton uses the game's own prefix.
Launching the exe directly skips the per-game Proton choice and the .NET-bearing prefix, so the manager
does not start.
¶ Mods
- 28 mods, the DX Enhanced preset, including AI HD Textures (about 1.1 GB) and AI HD FMVs (about 652 MB).
- Managed from
mods/in the game directory; saves live in the Proton prefix (compatdata/71250/...). - Undo:
flatpak run io.github.astrovm.AdventureMods restore.
¶ Where to get them
- Adventure Mods (astrovm/AdventureMods) sets up this preset on Linux: it finds the Steam install, downloads the mods, installs SA Mod Manager and .NET, sets resolution and load order, and can undo it all with
flatpak run io.github.astrovm.AdventureMods restore.list-mods --game sadxlists the presets and mods. - GameBanana hosts the individual mods under Sonic Adventure DX, including the large texture and FMV packs; manual installs go through SA Mod Manager.
- SA Mod Manager is the manager put in place of
Sonic Adventure DX.exe, and where mods are enabled and ordered after setup.
¶ Known issues
- Install URL 404s: the AdventureMods
.flatpakrefURL needs its full suffix. - "No supported games detected": the tool needs the app id in the
appsmap ofsteamapps/libraryfolders.vdf. Quit Steam once from its own UI; an SSHsteam -shutdowndoes not reach the running client. - .NET installer fails with code 203:
0xCB, "Failed to create main window". ExportDISPLAY=:0before setup; it is not the Proton version. - Setup looks stuck: the log writes in bursts. Watch the
mods/folder grow rather than the log, and give it several minutes.
¶ Rating
🥈 Silver. A commercial Windows release under Proton, with a 28-mod preset that makes it
look and run far better than the base game. Provisional: not run through for the wiki.
