Do you have a lot of UMD games? I got a PSTV (the Vita console), hacked it to use expanded memory (just follow the steps you can find online), and repurchased most of my physical catalog digitally. I think a lot of those games are locked at $10 since the store can no longer receive updates.

I still have my 1000 for physical. But even then, Vita incompatible games like Crisis Core and Spyro (for some reason the PS1 game isn't compatible with Vita) are available on my PS5.
