: High-end emulators like Mednafen (and its RetroArch "Beetle Saturn" core) require this exact binary to function properly and maintain hardware-level timing.

If your file matches this hash, you have a 1:1 perfect copy of the North American BIOS. If the hash does not match, the file may be a bad dump (corrupted) or a modified "hack" intended to bypass region locking.

However, to call it the "best" is to argue for .
