You’ve searched for a “Pokemon Omega Ruby update CIA decrypted,” and you’re worried about downloading the wrong file.
If you are on Citra, the decrypted CIA is the only way to fly. Just match your region, use FBI or Citra's CIA installer, and enjoy the nostalgia of soaring over Hoenn on Mega Latios/Latias.
Playing Omega Ruby without the v1.4 update feels broken. With it, the game sings—smoother performance in Mauville City, functional online GTS (via Pretendo or custom servers), and access to every Mega Stone.
