AetherSX2 remains one of the best ways to play PlayStation 2 games on Android, but setting it up can be tricky. One of the most common roadblocks is the frustrating “Failed to write BIOS image” error.
Take a deep breath, move that BIOS file into a subfolder, grant the right permission, and you’ll be playing Final Fantasy X or God of War II on your lunch break in no time. Have a different error? Let me know in the comments—I’ve probably seen it.
You select your BIOS file, the app seems ready to go, and then—nothing. Just that error message.
