Before I jump right into it, I have no experience exploiting the Switch. Anyways, I have a theory of how it would be possible to play Pre-Loaded games before they're actually released. Since the Switch contacts (I'm assuming) Nintendos server to verify the time of the games release and the current time, it would be possible to spoof the response of the server via a proxy or VPN server. If correct, essentially all that would be needed to do this is to spoof the response from the server, obviously easier said then done but it's just a theory. I was going to look into it a little more but this may spark an idea for someone who has a little more experience reading network packets and faking server responses. Lets hear some feedback about this idea, I'll keep you all posted if I find anything out.
