Agent X said:Peggle was never released as a Mini. There is a PS3 version, and there is also a separate PSP version. I don't believe the PSP version has all of the features of the PS3 version, such as online multiplayer and online scoreboards.
The Vita should be able to use the PSP version.
I think NGP/PSP2/Vita should get it's on version of the game or the PS3 PSN version.
