SafeDisc retail DRM does not work on Windows Vista and later (see Availability for affected versions).

Key points

Most of the fixes documented in this article target the DRM-free executable and will not work with other versions.
No in-game quit option. Must use Alt+F4 to quit.
3-4 player modes from the console versions are absent on the PC version and can only be played with up to 2 players.
Unfavorable to the console versions in many ways, including missing graphical elements (such as the heat wave effect in Egg Factory), characters' pupils being stationary in Story Mode cutscenes, FMV playback occasionally being choppy, and several in-game lines being excluded.


Source DRM Notes Keys OS
Disc check (requires the CD/DVD in the drive to play)

Essential improvements

Tweakbox for Sonic Riders

Work-in-progress, all-in-one mod that adds online multiplayer, widescreen support (without patching the game's executable file), controller support and more.
Requires Reloaded II. Installation instructions are available on the mod's GitHub page, website and this YouTube video.

Field of view (FOV)

Change FOV with Cheat Engine[citation needed]
  1. Download and install Cheat Engine.
  2. Download the WSGF attachment.
  3. Use the included Cheat Table file to adjust the FOV values.
Change FOV with hex edit[citation needed]
  1. Open d3dx9_25.dll with a hex editor such as HxD.
  2. Go to offset 0x3F9A9.
  3. Replace bytes 00 00 80 BF with bytes representing your float value multiplier at a negative value (default multiplier is -1.0). Remember to invert the byte order to Little Endian.


Use this online float to hex converter.
If the code is replaced with the command to jump to allow the extending of vertical fov at 0x3F9A9, replace bytes 00 00 80 3F at 0x1F8F3A with bytes representing your float value multiplier in a positive value (default multiplier here is 1.0).
FOV multiplier values lower than -0.75 or 0.75 will also cause blue clipping on geometry.

Multiplayer types

Type Native Players Notes
Local play
2 Versus
The PC version supports 4 player gameplay like the console versions without issues. However, the developers decided to disallow 4 players in the game's menu code and did not implement reading of inputs for players 3 and 4 (their input data is still stored). Through hacking, playing 4 players is possible.[7]
LAN play
Online play
Asynchronous multiplayer

Issues fixed

Game Lags when Rendering Lots of Particles (e.g. End of Red Canyon)

Set CPU Affinity to single core.[8]
  1. Open Task Manager.
  2. Go to the Details tab.
  3. Right Click SonicRiders.exe
  4. Press Set Affinity
  5. Check CPU 0, Uncheck all other boxes.

Note: The real fix is to hijack the Direct3D device creation; disable the D3DCREATE_MULTITHREADED flag (unused) and enable the D3DCREATE_DISABLE_PSGP_THREADING flag.

Infinite Loading Screen When Loading Race

Use decompressed game files.[9]
  1. Download Uncompressed Sonic Riders Assets.
  2. Extract to the Data directory of the game.

    This seems to be an issue caused by bad threading/lock mechanism between a thread that does decompression and a thread which reads file data from disk. It occurs when a lot of files are submitted to be decompressed at once and is more prominent on fast single-threaded CPUs. While I have not wrote a Reloaded-II mod that fixes the issue yet, I have decompressed the game files which should prevent this issue.
