However, the search for "resident evil 4 remake ps4 rom pkg update dlc link updated" will always be a cat-and-mouse game. Links die weekly. Scene groups rename files. Your best bet is to join a dedicated PS4 PKG Discord or Telegram channel where automated bots repost fresh mirrors daily.
Unfortunately, the official Resident Evil 4 remake is not available on PS4. However, if you're playing on a PS4, you can still explore other Resident Evil games, such as Resident Evil 7: Biohazard, Resident Evil Village, and the Resident Evil HD Remaster series.
