In simple terms, workbin is where Vita3K stores repackaged, emulator-ready assets extracted from official Vita packages ( .pkg files). Think of it as a pre-processed cache that helps the emulator load games faster without re-decrypting assets every time.

You are installing games manually via the ux0:app/ directory.
