Hi everyone,

I've been setting up AetherSX2 on Android again and noticed that different BIOS regions seem to give slightly different compatibility depending on the game. Most of the games I play run well, but I'm curious whether other users have found a particular BIOS version to be the most reliable.

While comparing different setup methods, I found some useful PlayStation emulator guides and BIOS information on https://ps2bios.com.br/, which helped me understand the differences between the available BIOS versions and emulator settings.

For those who regularly use AetherSX2:

  • Which BIOS region do you prefer (NTSC-U, PAL, or NTSC-J)?
  • Have you noticed any performance or compatibility differences?
  • Are there any Android settings that significantly improve FPS or reduce stuttering?
I'd love to hear what setup has worked best for everyone.
