If you downloaded the game as a PKG but want to add standalone DLC packs:
To utilize a PKG file, your PS3 must be running a custom environment:
Remember: Always dump your own games. The PS3 scene values preservation over piracy. By creating a PKG from your own disc, you ensure that John Marston’s story survives long after Sony shuts down PS3 store services completely.
To help tailor future guides or troubleshooting steps, are you using Custom Firmware (CFW) like Evilnat on your console?
Performance note: As of 2025, RPCS3 can run Red Dead Redemption at 4K 60 FPS on a high-end CPU (Intel i7 13700K or AMD Ryzen 7800X3D). The PKG format is preferred over disc dumps because it eliminates decryption errors.
