The process is straightforward, but it requires pinpointing the correct directory on your PC.
Locate Your Save: Right-click Super Smash Bros. Ultimate in your Yuzu game list and select "Open Save Data Location".
Backup Your Current Data: Before making changes, copy the existing files to a safe folder. This prevents progress loss if the new file is incompatible.

Note: Ensure the folder structure matches; usually, you should see a save_data folder or several alphanumeric files.
Launch and Verify: Restart Yuzu and boot the game. If successful, you should see the "All Characters Unlocked" notification or find the full grid in the character select screen. Troubleshooting Common Issues
Game Not Loading/Infinite Loop: If your game hangs on the versus screen after installing a save, it may be due to version mismatches (e.g., using a v13.0 save on a v1.0 game). Always ensure your game and updates match the save file's requirements.
Missing DLC Characters: A save file cannot "grant" you DLC you haven't installed. You must have the DLC files (.nsp or .xci) installed in Yuzu for those characters to appear, even if the save file says they are unlocked.
Spirit Graphics Issues: For a complete Spirit Board, some users recommend also installing BCAT files, which ensure all spirit images display correctly rather than as generic icons.
Using a 100% save file transforms your Yuzu experience from a single-player grind into a complete, tournament-ready package in minutes. Whether you are hosting a local smash fest or testing out high-level combos, this shortcut is a must-have for the dedicated emulator community.
