In the PlayStation 4 ecosystem, PKG files are the standard format for software distribution, representing a significant evolution over traditional disc-based or raw ISO formats. While "ROM" is a generic term for game files, for PS4 specifically, the PKG format is technically superior for installation, performance, and management on modern hardware. The Superiority of PKG Files for PS4
If you have multiple PS4 consoles (for example, one in the living room and one in a bedroom), moving your library is as simple as moving an external hard drive. With PKG files, you don't have to carry a wallet full of discs; your entire collection fits in your pocket on a portable SSD.

Reduced Hardware Wear: Launching games via PKG eliminates the need for the Blu-ray drive to spin up. This prevents laser wear-and-tear and avoids mechanical noise during gameplay. Portability If you have multiple PS4 consoles (for
Better for Updates: Game patches and DLC are almost always distributed as PKGs, making it easier to keep your library updated. PKG vs. FPKG In the jailbreak community, you will see two types:
Splitting for FAT32: For users limited by legacy storage formats, PKGs can be split into smaller chunks and reassembled during installation. Standard Installation Workflow
