PS2 save files come in various formats depending on the original region of the game. Before downloading a file, check your game's region ID code. You can find this code on the AetherSX2 game selection menu or inside the game settings (it usually looks like SLUS-XXXXX for North America, SLES-XXXXX for Europe, or SLPM-XXXXX for Japan). Go to a trusted emulation save database like GameFAQs. Search for Naruto Shippuden: Ultimate Ninja 5 . Navigate to the "Saves" section.
