AetherSX2 cannot read .zip or .rar files. The BIOS must be extracted so that only the uncompressed .bin file is placed in the BIOS folder.
On Android 11 and later, AetherSX2 may not have permission to access files. Ensure Storage or Files and Media permissions are enabled, and grant “All files access” if required.
If the file became corrupted during download, transfer, or storage, it won’t work properly even if detected.
File naming sometimes causes issues, particularly if you’ve renamed the BIOS file or it came with unusual characters in the filename.

ISO file quality and format can cause boot problems even with the correct BIOS.
