Getting the same thing mate! I've got like 40 ps mini games from ps plus and not 1 will load. All have that error code. Hope sony sorts it out ASAP.
Yeh me too. havent tried a mini Ive paid for yet but guesssing they work, something to do with ps+ and think we would have the same problem if we could play the ps one games on the vita, hopefully they will sort it soon.
