1. Download sqlite
2. Make yourself a bit familiar with the sqlite client tools
2. Set up a environment path or paste in your broken savegame right besides the sqlite binaries.
3. Run the command sqlite3 broken.vcdbs ".recover" | sqlite3 repaired.vcdbs, replace "broken.vcdbs" with your actual savegame name. This will try to fix any corrupted chunks.
