Sony has a (partial) solution for anyone who's purchased PSP and PSOne games in the past.

It ain't perfect, but it's something. Sadly, Vita games are left out in the cold.
Interesting... though I wonder why it says "select" games. Are they saying select because it'll only be for PS1 games that make their way to the PS4/5 store or because even if PS1 games are on the PS4/5 store, only a select number will qualify for download without re-purchase?
