If a user obtains a highly compressed ISO:

| Term | Meaning in Context | |------|----------------------| | | A disc image file format. An exact sector-by-sector copy of the original game disc. | | Highly Compressed | Use of lossless or lossy compression algorithms (e.g., 7-Zip with LZMA2, repacking, or CSO compression) to reduce file size. Often involves removing dummy data or re-encoding audio/video. | | Extra Quality | Claim that compression does not degrade gameplay, FMV (full motion video), or audio quality significantly. Often contradictory for extreme compression. | | PS2 | Target hardware/emulation platform. |

If you see a link claiming to offer God of War II in a ridiculously small size (like 50 MB or 200 MB), it is almost certainly a fake, a virus, or a scam. Real game data cannot be compressed that aggressively without breaking the game.
