PKG files are essentially packages that contain game data, including the game itself, artwork, and metadata. These files can be downloaded and installed on the PS3, allowing users to play PS1 games that may not have been officially re-released through the PS1 Classics program.

The PS1 (PlayStation 1) era was an incredible time for gaming, with classics like Final Fantasy VII, Metal Gear Solid, and Tomb Raider. And, as it turns out, many of these games are still playable on the PS3, albeit through some workarounds.
