Residents of North American can grab Mega Man Legends 2 from PSN right now for a cool $9.99. The game is playable on PS3... but there appears to be an error on Vita and PSP. Trying to download the game on Vita results in the message "cannot download using this system." Uh-oh?
Hopefully it's just a small hiccup that will be rectified soon. I'll keep an ear to the ground; more news on this soon.
UPDATE: PSP works if you connect directly to a PS3. It appears Vita is incompatible entirely, for one reason or another
UPDATE 2: Vita works! All you need to do is buy it from your browser on PS3, then check your download list on Vita. Alternatively, try searching for MML2 from the Vita Store.
