NeoGAF and Reddit users have discovered that PSone title Buzz Lightyear of Star Command appears to feature Vita emulator support for classic releases.
Just don't get too excited, though: it's not actually playable, meaning you can only install it on your handheld. Still, it's the first title to support the Vita in any way.
Sony has been actively working on bringing PSP and Minis titles to its latest handheld, with PSone classics expected to follow. It looks like we could be quite close.
