I did and will check tonight, thanks.
@steveb07 if you already bought it on psp then you should just be able to download it again. look at your download list via the ps store on the vita. it works on vita no probs. that,s assuming you use the same account on vita that you used on the psp.
Thinking about it I downloaded other games as well. I'm all excited now!
It was a UMD Megadrive collection...
