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

The original game was first released for the Dreamcast in North America on June 18, 2001, and the rest of the world on June 23. 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. This PC port is based off the GameCube version, with the expanded multiplayer and Chao Karate content being locked behind a separate DLC purchase.

Initially, it wasn't made available in Japan, but Sega later announced that the game will be available in Japan on January 23, 2024 alongside Sonic Adventure DX, marking the debut the PC version of Sonic Adventure 2 in Japan.

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 Modifications for recommendations and how to setup X-Hax's SA Mod Manager to ease the installation of mods.

Issues unresolved

Menus don't render

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

FXAA breaks the game

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

This issues is related to the older SA2 Mod Loader; use SA Mod Manager instead. Rebooting the computer with the mod loader uninstalled seems to help temporarily. 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

Game crashes after the Sonic Team logo

Use DXVK[citation needed]
Go to DXVK's project page. Download the latest release. Open it using a ZIP program, and go to the X32 folder. Copy d3d9.dll and paste it into <path-to-game>

Use ForceD3D9On12[citation needed]
Download the latest release Open it using a ZIP program, and go to the x86 folder. 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 SA Mod Manager offers an option to do that. If the game is crashing in both fullscreen and 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

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

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

Run the game at screen refresh rate

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]
Download Special K. Copy SpecialK32.dll to the installation folder. Rename SpecialK32.dll to d3d9.dll. Start the game and then exit. Open d3d9.ini in the installation folder. Change TargetFPS to 60.0. Change RefreshRate to 0.

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

Manually create config files

Go to the configuration file(s) location. If no files are present, create files named Keyboard.cfg and UserConfig.cfg. Copy and paste following to files. Keyboard.cfg: <?xml version="1.0" ?> <Setup Layout="0" /> <Players> <Player InputWay="1" Vibrate="0"> <key index="83" /> <key index="65" /> <key index="73" /> <key index="79" /> <key index="5" /> <key index="52" /> <key index="56" /> <key index="54" /> <key index="25" /> <key index="16" /> <key index="37" /> <key index="23" /> <key index="4" /> <key index="37" /> <key index="27" /> <key index="67" /> </Player> <Player InputWay="0" Vibrate="0"> <key index="22" /> <key index="18" /> <key index="0" /> <key index="3" /> <key index="102" /> <key index="98" /> <key index="101" /> <key index="99" /> <key index="66" /> <key index="104" /> <key index="37" /> <key index="76" /> <key index="105" /> <key index="37" /> <key index="28" /> <key index="111" /> </Player> </Players> UserConfig.cfg: <?xml version="1.0" ?> <Configs FullScreen="1" Display="0" Res="22" Width="640" Height="480" RefreshRate="60" Language="0" Analytics="0" /> Start the game from <path-to-game>\sonic2app.exe. 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

This fix requires SA Mod Manager.

Instructions

Modding essentials

The legacy version of SA2 Mod Loader can still be downloaded here from GameBanana for machines running Windows XP or newer. It is also compatible with Sonic Adventure DX.

How to install SA Mod Manager

Download the latest version of SA Mod Manager that matches the machine's CPU architecture from Github here. Extract the contents of release_x86.zip (32-bit) or release_x64.zip (64-bit) to <path-to-game>. Run SAModManager.exe, go to the Manager Config tab and ensure that Install Mod Loader is active, then go to the Game Config → Options tab and adjust settings as desired. Notes Adds optional tweaks such as skipping intro videos and company logos, locking the framerate for higher refresh rate displays, fixes for environmental mapping, particle effects, and screen fades, and disabling loading screen animations which also speed up loading times.
