This requires a USB drive and a hacked memory card.

1. Convert the File: Use a PC tool called "PS2 Save Builder." Convert the repack from .ps2 to .max.
2. Use uLaunchELF: On your PS2, run uLaunchELF from your Free McBoot card.
3. Copy via USB: Paste the .max file from your USB to your memory card.
4. Uncrush the Data: Use "PS2 Save Uncrush" to decrypt the file into raw data.

2. Transfer: Copy the save file to a USB drive formatted in FAT32.
3. Import: Boot the PS2 with the cheating device or FreeMcBoot. Use a file manager (like uLaunchELF) to copy the save from the USB drive to the PS2 Memory Card (MC0 or MC1).

1. Introduction

Naruto Shippuden: Ultimate Ninja 4 represented a turning point in anime fighting games, introducing the post-time-skip “Shippuden” storyline. However, the game’s unlock system was notoriously grindy: certain characters (e.g., “Sage Mode Naruto,” “Itachi (Anbu Black Ops)”) required hundreds of battles or specific combo trials. As the PS2’s lifecycle ended (ca. 2007–2010), a niche community of save-editing hobbyists emerged. Their goal: produce a definitive “100% complete repack” that bypasses unlock requirements entirely.

The term “repack” in this context is borrowed from warez scene culture, denoting a pre-configured, ready-to-use file. Unlike a simple uploaded save from a player who completed the game, a repack is deliberately constructed via external tools.

5. Region Compatibility (Critical!)

Ultimate Ninja 4 has multiple region versions: Title: Reverse Engineering and Repacking of Save Data

| Region | Code | Language | |--------|-------------|----------------| | Japan | SLPS-25844 | Japanese only | | USA | SLUS-21858 | English/Japanese voices | | Europe | SLES-55378 | Multi 5 |

Repack must match your game’s region – otherwise:

• Save won’t appear, or will show as corrupted.
• Some repacks are “converted” (e.g., JPN→USA) – rare but possible.
