In other news, had a slight scare with my PlayStation TV. It wouldn't let me play some PSP games, and some straight up gave me an error when I tried to start them. I was also told that I needed to re-download my PS1 games, but was unable to from the store.
It seems logging back in to the PSTV and rebooting fixed the issues.
I'm not confident that digital libraries will keep working once Sony finally drops support for the Vita and PS3. Fingers crossed I'm wrong.
