Info from my personal testing as well as NeoGAF (mostly NeoGAF)

That link also contains a list of games that are currently not known to work using this method (or are unknown).

I think Mega Man 2 ( Japan Import) works as well. But not from the store itself.  Do Crash Bandicoot and Spyro The Dragon work?

If you click the link Magi provided, you'll find a whole list of games that are not compatible.

Harvest Moon works too.  And it's a great game.

Would Media Go also work in transfering them to the Vita?  I'm sure there's at least one guy with a Vita and no PS3.

Sadly, Media Go does not recognize the Vita.

It's a dern shame that Vita owners have to jump through all of these flaming hoops just to get things to work like they should.

Harvest Moon and Castlevania are going to tide me over easily. Too bad FFV is the only FF that doesn't work, since it's the one PS+ gave us. And once Spyro and Crash work that's pretty much all I will need. But SCEA still needs to get things together. Just like it SHOULD be with PSP and minis, any future PS1 classics that are released need to be on the Vita day 1.

Well that sucks for anyone who doesn't have a PS3.  I'm sure their in the minority, but it still sucks.

Just paid $30 for FFVII and FFIX but I can't download them cause I don't have a PS3. Yay

You can still download 7 on the Vita.
