Would it be possible to use the iso format?

It's more practical for those who have the original game on CD, to convert it to iso, it would be nice to be able to leave it in iso to play, if that's not possible "ok"...

This is technically impossible due to the need for a real PS4 to decrypt the data, in addition, the pkg format has become the de facto standard for PS4 games, and returning to ISO would be pure madness.
