Use your hex editor to open sonicr.exe in the game’s installation directory (NOT the disc) and edit the following addresses: Get a hex editor such as xvi32 ( ), which is freeware. Note that you still need the disc to play, regardless. After setup is finished, you may simply copy and paste all of the disc’s data into the game’s installation directory. Don’t worry if this doesn’t properly copy all the files. Select Windows 98 Compatibility mode and check Run as Administrator and try again. If it fails to run, right click it, select Properties, then the Compatibility tab. Navigate to your Sonic R disc’s directory. Now back to the installation instructions: Find the drive Sonic R’s CD is inserted into and change it to a drive letter closer to the beginning of the alphabet than your other drive(s)’s letter (Right click the drive -> Change Drive Letter and Paths -> Change… and select a new letter). The setting can be found here: Control Panel -> All Control Panel Items -> Administrative Tools -> Computer Management. If you cannot place the CD into the first drive for some reason, you can change drive letters in the Control Panel. Only do this if absolutely necessary and you feel comfortable (if not, skip ahead!): This next step can and likely WILL cause issues with other games and software. It will NOT play the game OR music in any other drive. For example, if you have two DVD drives, D and E, the CD MUST be in D. IMPORTANT: Sonic R’s CD must be in the FIRST disc drive on your computer.

Simply place your Sonic R CD into the drive you wish to play it from. This step usually isn’t a problem for most machines.
