Ok, your problem is the vita isn't compatible with those titles, which was what I suggested with my first post. It has nothing to do with the region you live in. Sorry to say, they're ps3/psp only titles.
They are PS3/PSP titles only if you use a NA account, if you have an EU account they are compatible. Because, like I said before, they haven't been certified for use in NA.
Crash Bandicoot 1 - 3 has been available in Europe for Vita since August 2012: http://blog.eu.playstation.com/2012/08/27/ps-vita-
Spyro has been available since December 2012: http://blog.eu.playstation.com/2012/12/07/spyro-th
I do appreciate you trying to help, but you're wrong, and it's not helping. You can't argue against facts and evidence when the burden of proof is upon you.
Unfortunately, posting about it in a forum isn't going to do anything, even this one. Crash and Spyro aren't first party titles either. SCEA may have had their hand in publishing these older games, but Activision owns the rights to them, and it's their initiative to work things out with Sony to get the games working on the vita in NA. There may be other complications behind the scenes too. There are ways to get the UK versions of the games working on your vita, if you're willing to take the time to change your account activation, but that's completely up to you, and it's definitely far from ideal. That's probably the best solution though, aside from waiting for vita compatibility in NA. That, or investing in a ps3, or psp, but solution A, as time consuming as it is, is by far the one that will cost you the least.
