Key points

This port, as well as the Xbox 360, PlayStation 3, and later PC versions, was based on the GameCube version, which saw a multitude of changes that differ from the original Dreamcast version; see this blog or this video for details. Mods can either restore the missing/altered elements from the Dreamcast version, or enhance the features of the GameCube version in this port.
Includes the unlockable Game Gear games that are missing from later re-releases.
Poor quality PC port with inferior visual and sound quality compared to previous versions, broken windowed mode, lacks keyboard remapping, and a camera spinning bug with controllers, among other issues; see TCRF for details. A majority of these issues can be resolved with mods.

Issues resolved[edit]

Broken windowed mode[edit]

The game's windowed mode does not function properly and causes the game to be stretched out to 1434x730, regardless of resolution selected from the game's configuration tool, resulting in grainy and distorted graphics.
Install SADX Mod Loader (included with SADX Mod Installer) and use its graphics settings instead[6]

Controller causes camera to spin uncontrollably[edit]

Certain controllers may cause the game's camera to spin around and cannot be stopped unless constantly holding down the Whistle button.
Install Input Mod (included with SADX Mod Installer)[7]

This section assumes that you have already patched Sonic Adventure DX with SADX Mod Installer. The later re-releases needs to be downgraded first before modding the game.
SADX Mod Loader, included with SADX Mod Installer, eases installation of mods without replacing files, as well as configuring game settings and mod options (if available).
