Specifically, those purchased legally through the PSN Store. It seems like it should, but I can't find a definitive answer anywhere.

Best Answer
Update 1: PSOne Classics will come to the Vita August 28, 2012 (Joystiq)
Update 2: On August 28, PlayStation Vita firmware update 1.8 went live, enabling the Vita to play select PSOne Classics. IGN has a list of compatible PSOne games.
Update 3: At this point most, but not all, PSX classics are supported on Vita. As per a recent mixup, all PSX games were temporarily downloadable on PS Vita, and all of them work. The reason any remaining titles aren't available on Vita is likely due to licensing issues.
PS Vita didn't support PSOne/archive titles at launch. You will need to wait.
