To play compressed PS2 games, you need a powerful emulator. The old recommendation was DamonPS2 (which is now considered buggy and unethical due to stolen code). The new king is:

Modern Android devices face three bottlenecks when running compressed PS2 games:

Real-world tests with AetherSX2 show that running a highly compressed game (e.g., Shadow of the Colossus, original 5.7 GB → compressed 2.1 GB 7z) after extraction performs identically to uncompressed ISO. However, attempting to emulate directly from a 7z archive is impossible without full extraction, making “highly compressed playable” formats a misnomer.

Cons:

Recommendation: Use CSO for moderate compression with random-access support; use high-compression archives only if you can fully extract to a fast storage medium (internal UFS recommended).

Test and tweak: lower internal resolution, disable extra post-processing if frame drops occur.
