What if you don’t have a PC? If your PS3 runs Custom Firmware (CFW) like Evilnat or Rebug, you can install the PKG normally, then access the installed data via a file manager (multiMAN, Irisman). Go to dev_hdd0/game/ – each installed PKG has a folder named by its Title ID. Copy that folder to a USB drive. pkg extractor ps3
