If you work in the electronics department, you may have a chance at leaking the game. Grab the game, use a blade to carefully open the seal without tearing it, take the cartridge out and replace it with some shovelware (that way, when a coworker is counting inventory, they won't know). Go home, extract the rom from the cartridge onto your PC and upload it. When you're back at work, reopen the game case, switch the cartridge back, and seal it with tape once again.
