Dragrubis : Unless there is an official errata (and I insist on that one, since he doesn't consider any errata with the status "provisionnal" on being official) or a quote from a dev saying it works like that, my GM won't buy it : "the power says the sprite does a teamwork test with Hardware, so it will work only if you do a harware test, since that's how teamwork test works", more or less what he says, with "And I don't see how knowing how a smartgun internally works helps you using your gun".
And yeah, he is stubborn, but sadly I don't have a lot of other GMs to play with, so I make do.
