Sonic Adventure 2 is a cartoon third-person platform game developed by Sonic Team and published by Sega, and was released for PC on November 9, 2012. It is the sequel to Sonic Adventure.

The game was originally released worldwide on June 23, 2001 for the Dreamcast. It is historically notable for being one of the last games released for the Dreamcast and the final first-party game to be developed by Sega before becoming a third-party company after leaving the console market. It was also released during the 10th Anniversary of the Sonic the Hedgehog franchise. Sonic Adventure 2 restructures and streamlines the gameplay elements from its predecessor, featuring "Team Hero" (Sonic, Tails, and Knuckles) and "Team Dark" (Shadow, Dr. Eggman, and Rouge) with platforming, mech shooting, and treasure hunting Action Stages, all played in sequential order.

The game was later ported to the GameCube in 2002 as Sonic Adventure 2: Battle as an updated version of the game, featuring an expanded multiplayer mode and readjusted gameplay elements. Despite being ported to newer hardware, it also has simplified fog, missing vertex and colored lighting, and some content that are changed or missing compared to the original Dreamcast version. See TCRF for details and this video for cutscene-related changes. Similarly to Sonic Adventure DX and its subsequent ports, the 2012 PC port of Sonic Adventure 2, as well as the Xbox 360 and PlayStation 3 versions, was based off the GameCube version, with the expanded multiplayer and Chao Karate content from Sonic Adventure 2: Battle being locked behind a separate DLC purchase.[1]

The game's physics and speed are tied around 60 FPS, meaning slowdowns on lower end machines and speedups with high refresh-rate displays. Various mods are available to restore original features from the Dreamcast version and address issues with the PC version; see Moddifications for recommendations and how to setup MainMemory's SA2 Mod Loader to ease the installation of mods.

Issues unresolved[edit]

Steam API Compatibility (Controllers)[edit]

When using any controller under the Steam Controller API, analog sticks are treated as digital keyboard keys and will be considered as 100% analog for all values beyond the dead zone.[citation needed]

Menus don't render[edit]

On AMD cards, menus won't render if the resolution exceeds 4579 x 3965, on either axis.[citation needed]

FXAA breaks the game[edit]

Forcing FXAA through the graphics card control panel will cause the game to stop responding.[citation needed]

Game freezes and hardlocks when trying to load a stage[edit]

This issues is related to the SA2 Mod Loader. Rebooting the computer with the mod loader uninstalled seems to help temporarily.[5] An issue ticket can be found on the Mod Loader's GitHub repo. Another potential solution is to to launch SA2 Mod Loader, click "Uninstall loader" to disable the mod loader, launching the game normally via Launcher.exe and exiting the game, and then re-launching the Mod Loader and clicking "Install Loader" to re-enable it.

Issues fixed[edit]


Using a Vulkan Wrapper[citation needed]
  1. Go to dxvk's project page.
  2. Download the latest release.
  3. Open it using a ZIP program, and go to the X32 folder.
  4. Copy d3d9.dll and paste it into <path-to-game>
Fixing crashes[citation needed]

If the game is crashing only in fullscreen mode, an easy workaround is to use a borderless fullscreen tool to make windowed mode fill the entire screen. The SA2 Mod Loader offers an option to do that.[6]

If the game is crashing in both fullscreen & windowed mode:

  • Disable any framerate limiters; Sonic Adventure 2's loading screens rely on uncapped FPS in order to load properly.[citation needed]
  • Disable any overlays (e.g. Steam Overlay, GeForce Experience).
  • For Nvidia cards, open Nvidia Control Panel, click Manage 3D Settings, Program Settings, and add sonic2app.exe.
  • Set V-Sync to On and set Preferred refresh rate to Application-controlled, then click Apply.

Game freezing for few seconds randomly[edit]

Fixing crashes[citation needed]
  • For Nvidia cards, open Nvidia Control Panel, click Manage 3D Settings, Program Settings, and add sonic2app.exe.
  • Set Power management mode to Prefer maximum performance, click Apply.

Missing or broken graphical effects[edit]

Some effects such as rain, fire, smoke, footprints, and dirt from digging as Knuckles or Rouge are missing on integrated graphics with application optimization mode enabled.
Disable Application Optimal Mode from the integrated GPU control panel[7]

Run the game at screen refresh rate[edit]

Fullscreen mode is limited to 60 Hz, even if the screen refresh rate is set higher than that.
Set screen refresh rate and 60 FPS cap[citation needed]
  1. Download Special K.
  2. Copy SpecialK32.dll to the installation folder.
  3. Rename SpecialK32.dll to d3d9.dll.
  4. Start the game and then exit.
  5. Open d3d9.ini in the installation folder.
  6. Change TargetFPS to 60.0.
  7. Change RefreshRate to 0.

Launcher crashes when trying to start the game, No resolution options available[edit]

Manually create config files[8]
  1. Go to the configuration file(s) location.
  2. If no files are present, create files named Keyboard.cfg and UserConfig.cfg.
  3. Copy and paste following to files.
    • Keyboard.cfg:
    <?xml version="1.0" ?>
    <Setup Layout="0" />
    <Player InputWay="1" Vibrate="0">

    <key index="76" />
    <key index="105" />
    <key index="37" />
    <key index="28" />
    <key index="111" />
    • UserConfig.cfg:
    <?xml version="1.0" ?>
    <Configs FullScreen="1" Display="0" Res="22" Width="640" Height="480" RefreshRate="60" Language="0" Analytics="0" />
  4. Start the game from <path-to-game>\sonic2app.exe.
  5. If everything works, then change the values in UserConfig.cfg to desired ones. Bypassing the launcher is also recommended afterwards.

Planted Trees in the Chao Garden appear as saplings despite being fully grown[edit]

This fix requires SA2 Mod Loader.
  1. Download and install SA2 Mod Loader.
  2. Download the Enhanced Chao World mod.
  3. In the mod manager, tick and enable the mod, then click Configure and toggle any preferred features of the mod. The tree scaling fix is not listed as it is a part of the mod.

  • Highest Quality Textures - Replaces the textures with their highest-quality versions.
  • Dreamcast Characters - Dreamcast character models converted for the PC version. This results in consistent model quality between cutscenes and gameplay when used in conjunction with Cutscene Revamp, as most cutscenes use these models by default in the vanilla game.

  • Dreamcast Enemy Textures - Restores the original Dreamcast textures for the enemies.
  • Dreamcast Shield Hunters - Restores the original Dreamcast version of the G.U.N. Hunters and Shield Hunter enemies.

  • Ripple Fix - Fixes and restores the original Dreamcast version's water ripple effects.
  • Kart Stage Water Fix - Fixes the broken water texture in the kart racing stages caused by the fog effects introduced in the GameCube version by removing them to closely resemble the original Dreamcast version.

  • Rouge's Eye Animation Fix - Fixes a bug with Rouge's eye texture when climbing along walls sideways.
  • Restored G.U.N. Logos - Fixes a transparency sorting issue with the G.U.N. robots that causes the G.U.N. logo to be missing. This mod also features an option to restore the transparency effects of the Artificial Chaos enemies from the Dreamcast version, but the floating variant have buggy transparency effects and are disabled by default as a result.

  • GameCube Textures - Replaces the textures of the game with ones leftover from the GameCube port.
  • Neuro AI HD Texture Pack - Enhanced HD-quality textures upscaled 4x by Gigapixel AI using neural networks.
  • Clean Loading Screen Ring - Removes the visible compression artefacts from the spinning ring sprite on the loading screen, using the BC1Smooth2 ESRGAN model.
  • "Unstretched" Stage Select ARK - Makes the Space Colony ARK portion of the Stage Select screen appear unstretched similarly to the Xbox 360 and PlayStation 3 versions by resizing the image to 4:3 during the transition between the Earth and ARK portions.
  • Dreamcast Credits Images - Restores the original credits screenshot images from the Dreamcast version while using the higher poly GameCube models.


  • Disable Upgrade Models - Disable or show upgrade items on characters.

  • No Loading Screen Tips - Removes the gameplay tips that appear during a loading screen which may not be readable by default due to the faster loading times of the PC version.
  • Loading Screens Are Stupid - An alternative to the above, which removes Omochao, gameplay tips, the spinning ring sprite on the loading screens to make them resemble the Dreamcast and GameCube versions.
  • Character Select Mod - Allows players to play as other characters in stages they weren't intended for by pressing certain buttons while loading a stage.
  • Higher Draw Distance - Increases the rendering draw distance for most objects. Not recommended for gameplay.
  • Idle Chatter SA2 Edition - A port of the similarly named Sonic Adventure DX mod for Sonic Adventure 2 that adds the ability to hear what the player's character has to say about the current stage. The function is mapped to Right on the D-pad due to the Input Mod not being available for Sonic Adventure 2.
  • Chao World Extended - adds new contents to the Chao Garden, while bringing back unused contents and adding a variety of ways to get a new kind of chao

Co-op Story Mode[edit]
