Squarehard, turns out I need the following:
Army Corps of Hell
Hyperdimension Noire (Kid drooled on this one)
Valhalla Knights 3
Superbeat Xonic (I have that $100 limited edition with the vinyl records, and I kinda don't want to open it)
Once I am able to find those, the ENTIRE vita collection should be complete!
Just to save Squarehard some time, i've already got scans for Hyperdevotion Noire.
Credit goes to Thulsa790 on reddit. He's the guy who originally posted a bunch of vita scans and I asked him a while ago if he had Hyperdevotion Noire. Luckily he did, but I was too lazy to post it here.
