To run AetherSX2 smoothly on your Android device, your phone or tablet must meet certain hardware and software specifications. The AetherSX2 system requirements begin with Android 8.0 or higher, but for stable performance with most PS2 games, a device powered by a Qualcomm Snapdragon 845 processor or better is strongly recommended. Since the emulator is CPU-intensive, older or entry-level devices may struggle with demanding titles. It is advisable to have at least 4GB of RAM, and a capable GPU is important for enhanced rendering and resolution upscaling. For the best gameplay experience, your device should offer strong single-core performance and enough internal storage space to handle PS2 BIOS files and large game ISOs.
