If your Sonic Generations mods aren't loading or are causing the game to crash, the issue usually stems from an outdated mod loader, incorrect file paths, or configuration mismatches. Essential Troubleshooting Steps
Verify Game Files: Steam users can fix many issues by right-clicking Sonic Generations in their library, selecting Properties > Installed Files, and clicking Verify integrity of game files. This restores missing or corrupt core files that mods may have accidentally altered.
Update HedgeModManager: Ensure you are using the latest version of HedgeModManager (HMM). If the mod loader isn't working, navigate to Settings in HMM and click Install Mod Loader to re-enable it.
Fix Configuration Errors: If the game won't launch at all, delete all .cfg files in the Sonic Generations install folder, then run the Configuration Tool again to reset your display settings.
Adjust Load Order: The order of mods in your manager matters. Place essential fixes like the Direct 3D11 renderer at the top, and put larger gameplay overhauls (like the Unleashed Project) above smaller cosmetic mods to prevent overwriting critical data.
Antivirus Interference: Some antivirus programs block the mod loader from installing. Check your antivirus logs and add an exception for HedgeModManager.exe and your game folder if necessary. Specific Platform & Hardware Fixes sonic generations mods not working link
Steam Deck / Linux: If mods fail to load on Steam Deck, you may need to manually place a 64-bit mscoree.dll in the game's executable directory or use Protontricks to fix the cpkredir.ini file paths.
RTX Graphics Cards: Some users report incompatibilities between older mods and modern RTX cards. Using the Direct 3D11 renderer mod can often bypass these legacy issues.
Manual Mod Installation: If "1-Click" installs from sites like GameBanana fail, try downloading the mod manually and using the Add Mod button in HedgeModManager to select the .zip or .7z file directly.
Are you experiencing a specific error message like "Configuration Mismatch," or does the game simply close without warning?
