What it does
Shenmue Companion reads the real VMU save, lets you play Shenmue-flavoured side activities on the VMU Pro, then writes the results back with the proper integrity checks so the original game accepts everything cleanly.
It is less about spectacle and more about extending the feeling of the game: small rituals, side earnings, capsule collecting, and that oddly comforting texture Shenmue gives to ordinary things.
