Super Smash Bros Ultimate Unlock All Characters Yuzu Online

Review: Super Smash Bros. Ultimate – "Unlock All Characters" (Yuzu)

Verdict: Functional, Stable, and Essential for Multiplayer, but Spirit-less.

For players using the Yuzu emulator to run Super Smash Bros. Ultimate (SSBU), the grind to unlock the 74+ base roster characters can be a significant hurdle. While the "World of Light" adventure mode is a fun journey, users looking to quickly jump into local multiplayer or test specific matchups often seek a pre-unlocked save file.

This review covers the reliability, installation process, and functionality of community-sourced "100% Unlock" save files. super smash bros ultimate unlock all characters yuzu

2. The Installation Process (User Experience)

On Yuzu, the process is incredibly streamlined compared to other emulators.

  1. Location: Right-click the game in the Yuzu list -> "Open Save Data Location."
  2. Execution: Delete existing files (optional) and paste the downloaded save files.
  3. Result: Instant access to the roster upon boot.

There is no complex patching required. It is a "plug-and-play" experience that even novice emulator users can handle. Review: Super Smash Bros

4. Technical Challenges

  • Version mismatches: Game and DLC updates change save structures and memory addresses.
  • Integrity checks: Nintendo/SSBU may use signature or integrity checks that, if triggered, can corrupt or block saves.
  • Emulator differences: Yuzu’s handling of file paths, save formats, and memory mapping differs from a real Switch.
  • Corruption risk: Incorrect edits can corrupt save files, requiring backups.

6. Best Practices and Recommendations

  • Use legally obtained game backups and own the original cartridge/license.
  • Keep original save backups before editing.
  • Limit modified saves to offline, personal research or single-player use; avoid online play with modified data.
  • Prefer official DLC for content access when possible.
  • Document all steps and maintain versioned backups for reproducibility in research.
  • For academic work, focus on reproducible methods and disclose sources for tools used.

3.5 DLC and Updates

  • Description: Some characters are added via official DLC—ensure the game has appropriate updates/DLC.
  • Pros: Official and legitimate.
  • Cons: Requires purchasing DLC; emulator compatibility for DLC may vary.

Method 1: The "Vanilla" Grind (Fastest Legit Method)

If you want to earn the characters legitimately without cheats or mods, you need speed. The standard rules for unlocking characters in SSBU are:

  • 1 new fighter every 10 minutes of gameplay.
  • Unlocking via Classic Mode (1 character per clear).
  • Unlocking via World of Light.

However, you can abuse the system on Yuzu by resetting the internal timer. Location: Right-click the game in the Yuzu list

✅ Method 2: Enable “Unlock All Characters” Cheat Code

  1. Right-click the game in Yuzu → Open Mod Data Location.
  2. Create a folder named cheats if it doesn’t exist.
  3. Inside, create a text file with the game’s build ID (e.g., 01006A800016E000.txt).
  4. Add this cheat code (for latest game version):
[Unlock All Characters]
04000000 0037cd0c 52800020
04000000 0037cd10 d65f03c0
  1. In Yuzu, right-click the game → Properties → Cheats tab → enable the cheat.
  2. Launch the game → all characters unlocked.

Some codes require matching game version (e.g., 13.0.0). Update your game and Yuzu.
