Use (free, open-source). Right-click the archive > 7-Zip > Extract to "Naruto Ultimate Ninja 3" . The output should be a standard .iso file of roughly 4.1–4.3 GB. If the extracted file remains tiny, you downloaded a fake.
Also, to Naruto_Ultimate_Ninja_3_Compressed.iso – some emulators misdetect highly compressed files as corrupted if the name contains special characters.
Naruto: Ultimate Ninja 3 is audio-heavy. In a highly compressed scenario, the emulator must constantly decompress data sectors. On low-end hardware (such as budget Android phones), this can cause "audio popping" or stuttering during the "Ultimate Jutsu" cinematic animations because the CPU cannot decompress the video and audio streams fast enough to feed the emulator.
If you tell me which or device you are using, I can provide a custom settings guide to fix any lag or graphical glitches.
