AetherSX2 & NetherSX2 BIOS Setup Guide (Android)
AetherSX2 brought full-speed PS2 emulation to Android. Development ended in 2023 — new users should install NetherSX2, the community continuation. Setup is identical.
AetherSX2 vs NetherSX2 — Which One?
AetherSX2 was the original Android PS2 emulator, pulled from Play Store in 2023. NetherSX2 (GitHub: Trixarian/NetherSX2-patch) continues it with bug fixes and no ads. Choose NetherSX2 for fresh installs.
1. Install the App
Download NetherSX2 from the official GitHub Releases — never from random APK mirrors. Allow Install unknown apps, then open the APK.
2. Import Your BIOS
Copy your dumped .bin BIOS to a folder (e.g. Internal Storage › PS2 › BIOS). On first launch tap Import BIOS and select the file.
3. Recommended Settings
- Start with Optimal / Safe preset.
- Use Vulkan renderer on modern phones.
- Keep internal resolution at 1x initially.
4. Load Games and Controllers
Place legally dumped game images (ISO/CHD) in a games folder. Pair a Bluetooth gamepad for best controls. Minimum: Snapdragon 845, 4GB RAM, Android 7.0+.
