Step1:

Download the APK

Download the compatible AetherSX2/NetherSX2 APK from a trusted source and save it on your Android device.

Step2:

Install the APK

Open the downloaded APK and allow Install Unknown Apps if Android asks for permission. Tap Install and wait for the installation to finish.

Step3:

Set Up the BIOS

Open the emulator and select your legally obtained PS2 BIOS file. A BIOS is required to run PS2 games.

Step4:

Add Your Games

Create a folder for your PS2 game files and give the emulator access to it. Scan the folder to add your games to the library.

Step5:

Adjust the Settings

Start with the default graphics settings. If a game runs slowly, lower the resolution or try switching between Vulkan and OpenGL.

Setting Up the PS2 BIOS (Critical Step)

A PS2 BIOS is required before AetherSX2 or NetherSX2 can start your games. It is not included with the emulator because the BIOS is copyrighted. The safest option is to dump the BIOS from your own PS2 and transfer it to your Android phone.
Add Your BIOS File

Dump the BIOS from your PS2 and transfer the file to your Android device.
Create a dedicated folder such as PS2/BIOS and place the BIOS file there.
Open NetherSX2 and go to Settings → BIOS → BIOS Files.
Browse to your BIOS folder and select the file.
Check that it appears as the active BIOS before launching any game.

Adding and Playing Games

Prepare your PS2 game files in ISO, CSO, or CHD format
In NetherSX2, tap “Add Game Directory”
Select the folder containing your game files
The emulator will scan and display your games with cover art
Tap any game to start playing

Device	Renderer	Upscaling	Frame Skipping	Recommended Settings
High-End – Snapdragon 865+	Vulkan	2×–4×	Off	Enable widescreen patches for supported games
Mid-Range – Snapdragon 720G–855	Vulkan	1×–1.5×	Auto if needed	Switch to OpenGL if Vulkan causes glitches; close background apps
Low-End	OpenGL	Native (1×)	Enable if needed	Use Fast/Unsafe preset and focus on lighter games
