The day is finally here everyone. After months of waiting and having trophies that are local only, the 1.80 firmware on Vita allows trophies from Treasures of Montezuma Blitz to be sync’d to the PlayStation Network. All you have to do is launch TOM Blitz one time and then go to the trophy app.
Alawar Entertainment said before that it was a “systemwide problem for all early-released free games.” And that “Sony is aware of the issue, and they recognised it as their responsibility to fix it in the next Vita firmware update.”
So it looks like Sony kept up their end of the bargain. Now there is nothing really stopping you from playing one of the best games on Vita.
