Why Use a Pre-Made Save File?

While unlocking everything in Super Smash Bros. 64 is a rite of passage for many players, using a 100% save file offers several distinct advantages:

Time Efficiency: Skip the hours required to unlock all four secret characters, the secret stage, and both secret modes.
Restoration: Recover lost progress if your emulator save file becomes corrupted.
Multiplayer Ready: Perfect for party play with all characters and stages available immediately.
Complete Experience: Access everything the game has to offer without the grind.

📁 Save File Location

Before installing the new save, you need to know where to place it. For Super Smash Bros. 64, saves are stored in different locations depending on your emulator. Important: On original N64 hardware, save data is stored directly on the game cartridge’s EEPROM chip and cannot be easily transferred without specialized hardware .

Project64 Emulator

[Project64 Installation Folder]\Save\

Save files use the .eep extension for EEPROM saves (which Super Smash Bros. 64 uses) . The save file must have the exact same filename as your ROM (e.g., if your ROM is “Super Smash Bros (USA).z64”, the save file should be “Super Smash Bros (USA).eep”).

RetroArch / Mupen64Plus

[RetroArch Folder]\saves\

For RetroArch using the Mupen64Plus core, save files typically use the .srm format. You can rename a .eep file to .srm as long as the filename matches your ROM.

Mupen64 (Standalone)

[Mupen64 Folder]\saves\

Similar to Project64, Mupen64 uses .eep files for EEPROM-based games.

Original N64 Hardware

On a physical Nintendo 64 console, save data is stored on the game cartridge itself, not on a memory card . To transfer a save file to a physical cartridge, you would need specialized hardware such as:

Retrode: A device that allows you to dump and restore saves from original cartridges
Gameshark Pro: Some versions allow save backup/restore
EverDrive: A flash cartridge that can load ROMs and save files from an SD card

For most players, using this save file with an emulator is the simplest approach.

⚙️ Installation Guide

Follow these steps to safely install your new 100% save file:

Step 1: Backup Your Existing Saves

Navigate to your emulator’s save folder (e.g., [Project64]\Save\).
Copy any existing .eep or .srm files to a safe location (like your desktop) to backup your current progress.
This step is crucial if you want to preserve your existing save data.

Step 2: Download and Extract the Save File

DOWNLOAD

Alternate Link

DOWNLOAD

Click the download link to obtain the save file. It will be in a .zip or .rar format.
Use WinRAR, 7-Zip, or Windows’ built-in extraction tool to extract the contents .
You should see a file with a .eep extension.

Step 3: Rename the Save File (If Necessary)

Find your Super Smash Bros. 64 ROM file. Note its exact filename (including region, e.g., “Super Smash Bros (USA).z64”).
Rename the downloaded save file to match your ROM filename, but keep the .eep extension.
Example: If your ROM is “Super Smash Bros (USA).z64”, rename the save to “Super Smash Bros (USA).eep”.

Step 4: Copy the Save File

Copy the renamed .eep file into your emulator’s save folder.
If you’re using RetroArch, you may need to rename the extension to .srm instead.
If there’s already a save file with the same name, replace it (after backing up).

Step 5: Launch the Game

Start your emulator and load Super Smash Bros. 64.
You should now have all characters and stages unlocked!
To verify, check the character select screen for Captain Falcon, Jigglypuff, Luigi, and Ness. Also check the stage select screen for Mushroom Kingdom .

Frequently Asked Questions (FAQ)

Is this save file safe to use? Will it work with my emulator?

Yes, save files for N64 emulators are completely safe to use. This save file works with Project64, Mupen64, RetroArch (Mupen64Plus core), and most other N64 emulators. The key is to ensure the save file has the correct filename and extension to match your ROM.

Does this work with the Virtual Console version on Wii/Wii U?

The Virtual Console version of Super Smash Bros. 64 uses a different save structure than the original N64 cartridge. This save file is designed for emulator use. However, you can use a tool like SaveGame Manager GX to import the save if you have a modded Wii .

How do I know if the save installed correctly?

After loading the game, check these indicators:

On the character select screen, all 12 characters should be visible (no question marks).
On the stage select screen, Mushroom Kingdom should appear as a stage option.
Go to the Data menu to check if Sound Test and Item Switch modes are available .

Can I use this save on original N64 hardware?

On original N64 hardware, save data is stored directly on the game cartridge, not on a memory card . Transferring a save to a physical cartridge requires specialized hardware such as a Retrode or EverDrive. For most users, using this save with an emulator is the most practical option.

What’s the difference between .eep, .fla, and .sra save files?

Different N64 games use different save chip types:

.eep (EEPROM): Used by Super Smash Bros. 64 and most early N64 games
.fla (FlashRAM): Used by games like Majora’s Mask and Pokémon Stadium
.sra (SRAM): Used by games like Ocarina of Time

For Super Smash Bros. 64, you need the .eep format.

The save doesn’t appear. What do I do?

If the save doesn’t work, try these fixes:

Ensure the save file has the exact same filename as your ROM (including capitalization).
Check that the file extension is .eep (or .srm for RetroArch).
Make sure the save file is in the correct folder—Project64 uses the Save folder, not the ROM folder.
For Project64, go to Options → Settings → Directories and verify the save directory path.
Launch the game once to generate a save file, then replace it with the downloaded one.

About Super Smash Bros. 64

Super Smash Bros. was released on the Nintendo 64 in 1999 and revolutionized the fighting game genre. Unlike traditional fighting games like Street Fighter or Tekken, Smash Bros. focuses on knocking opponents off the stage rather than depleting a health bar . Key features include:

Unique Damage System: A percentage counter that increases as fighters take damage—higher percentage means being launched farther
Simple Controls: All characters use the same button combinations for attacks, making it accessible to newcomers
Nintendo Crossover: The first game to bring together characters from Mario, Zelda, Pokémon, Metroid, and other Nintendo franchises
Multiplayer Focus: Designed for up to 4 players, it became a party game staple

The game was developed by HAL Laboratory under the direction of Masahiro Sakurai, who famously created a prototype called “Dragon King: The Fighting Game” before Nintendo approved the crossover concept . It sold over 5 million copies worldwide and spawned a beloved franchise that continues today with Super Smash Bros. Ultimate on Nintendo Switch .
