How to Load PS2 ISOs (Complete Step-by-Step Guide)

Learn how to load PS2 ISOs on PC and Android using PCSX2 and AetherSX2. This guide explains BIOS setup, ISO formats, folder structure, and common fixes—legally and correctly.

What Is a PS2 ISO File?

A PS2 ISO is a disc image copy of a PlayStation 2 game DVD.
Emulators do not read physical discs directly; they load ISO-based disc images.

Supported PS2 game formats:

• .iso ✅ (recommended)
• .bin
• .img
• .mdf
