I'm still waiting for Spyro and Crash! Europe has both of those on PS Vita!
Those are the 6 games I bought about a year ago to play on PS Vita (I bought 'em just before the Vita came out), and they still don't work!
It also looks like Europe has a whole Spyro bundle that costs less than buying them individually (like I did), and it works on PS Vita. The icon on the online PS Store shows the US flag on the icon of the trilogy too... But we don't get it.
I feel like playing Yu-Gi-Oh. One of those childhood games that I've never completed due to the lack of a memory card. : /
