Where's the PS1 Games?

Why won't Sony bring all the PS1 games to the PSN store. I've never seen a PS1 game in a retail store in many years and it would seem like porting the games over would be easy.

I doubt they are ever going to bring all or even most of the PS1 games to the PSN store, but it would be nice to see games like FFVII in the American PSN store. That's the 2nd best selling PS1 game for heavens sake...The Japanese PSN store has a ton more to choose from :( Amnesiac23

What's stopping them though? It seems like it would be easy money for them.

my god i would love that,i want to play the original valkyrie profile
