Key points

Supports networked multiplayer if .exe file is replaced with the officially-released network version of the game. This version includes all content found in the original release and is hex-edited to work on modern versions of Windows.
DXWnd (OG Edition) is required for the game to recognize input devices on modern versions of Windows. "Hook DirectDraw", "Fullscreen", and "Hook DirectInput" must be enabled within the program for the game to work.
The Sonic R Mod Loader is only supported by the more-compatible 2004 release of the game. You can use the Sonic R Updater to update your game.
Some reprints of the game are missing the music.
Hex-edited version of the original .exe also exists for those who are interested.
Configuration files can be edited to increase resolution and draw distance beyond what in-game menus allow.

Essential improvements[edit]

Sonic R Updater[edit]

Upgrades the game to its rare 2004 re-release, fixes compatibility issues with modern Windows systems, removes the disc check, adds modding support thanks to Sonic R Mod Loader, custom resolutions and widescreen support, windowed/borderless fullscreen modes, and loading music from the installation folder instead of the disc.
Network Mode is lost as a result of the 2004 re-release almost completely losing this feature.
How to install Sonic R Updater[1]
  1. Install Sonic R from the disc or copy the contents of the disc to a convenient location on your computer.
  2. Download Sonic R Updater from the link above or its Github page.
  3. Run sonic_r_updater_*.exe and follow its instructions. If the patcher does not auto-detect the game's installation folder, point it to <path-to-game> manually.
  4. Adjust graphics settings from the Graphics tab of Sonic R Mod Loader and enable desired mods from the Mods tab, then click Save & Play to save your settings and launch the game.

Featured Mods:[edit]

Some of the featured mods are included with Sonic R Updater.
  • RemoveStrays - A fix for various graphical bugs tied to how the game maps textures for the UI.
  • Widescreen Assets - Readjusts and crops the original 4:3 GUI assets to properly fit in 16:9 instead of stretching them. This also fixes banner in menus so they don't abruptly cut off when playing in widescreen.
  • Resort Island Fix - Fixes out-of-place floormaps of Resort Island.
  • Sega Saturn Style Colors - A mod that fixes and restores vertex colors. This makes the game look more lively and colorful than it did before. Additionally it makes Radiant Emerald translucent like its Saturn counterpart.
  • Gems Collection Textures - Ports over the textures featured in the Sonic Gems Collection version of the game.
  • ADX Music - A mod to use more efficient looping ADX format audio for music instead, opting for improved version of tracks from the Sega Saturn version in some cases.
  • Music R - A mod that changes most if not all of the music in the game.
  • Gentle Ring Sound - Replaces the loud and grating stock ring pick-up sound effect from the 2004 version that can cause audio clipping issues with a softer, sound-balanced one.
  • Improved SFX - A sound effects enhancement mod that replaces the default sound effects with higher quality ones.
  • Sonic 3D Blast Sounds - Replaces the default sound effects with ones from the Sega Saturn version of Sonic 3D Blast.
