: Some sites offer "God of War 3" for mobile emulators like PPSSPP . These are often the PSP titles Chains of Olympus or Ghost of Sparta renamed to attract downloads.

Many "highly compressed" links are clickbait designed to lead users to surveys, ad-heavy sites, or malicious software [4]. How to Actually Play It

For those looking to save data while maintaining "Extra Quality," these fan-made versions focus on several optimizations:

God of War 3 was released on a dual-layer Blu-ray disc, taking up roughly 35 GB to 40 GB of data. A standard PS2 DVD can only hold up to 4.7 GB (or 8.5 GB for rare dual-layer PS2 discs). It is physically impossible to compress a 40 GB PS3 game into a working PS2 format. Decoding the "Highly Compressed Extra Quality" Myth

You must obtain a legal digital copy or dump an original PS3 Blu-ray disc into a valid decryption format (.ISO or folder structure).

If you want to play God of War 3 on your computer (which is why you are searching for a PS2 ISO in the first place), you need to abandon the PS2 emulator.
