GRID0 ofw

Play Switch games online with friends over a virtual LAN (GRID0).
Original Firm-Ware (ofw) build for stock Switch 1 and 2, for Unmodded Switch Users.

_{Replaces the old LAN-play relays with better stability, faster speeds, and an easier setup.
Works for cross-play with banned switch users and emulator users. Fork of switch-lan-play, runs on ZeroTier. More info at GRID0.}

Setup Guide

Stock consoles cannot execute background custom modules. GRID0-ofw runs on a PC connected to the same home network, capturing and translating LAN-Play packets automatically.

1. Download the latest release from the releases page and open GRID0-ofw.
2. GRID0-ofw will automatically install ZeroTier One and npcap.
   For certainty:

   Make sure they are installed (it should say ZeroTier One and npcap are installed in the GRID0-ofw settings).
   
3. GRID0-ofw will automatically launch ZeroTier and connect to the GRID0 network.
   For certainty:

   Windows: Click the Up arrow at the bottom right of your screen and right-click the ZeroTier tray icon, make sure the status is OK in 8bd5124fd68185ec GRID0.
   
4. GRID0-ofw will automatically select the correct ZeroTier adapter.
   For certainty:

   In GRID0-ofw, open Settings, the relay will automatically connect to the presumed ZeroTier connection, but make sure the ZeroTier connection selected looks like the correct one (should be named something similar to ZeroTier).
   

Automatic Mode (Easier, Windows and Hotspot Capable Only):

5. Go back to the Play section of GRID0-ofw, make sure Automatic (DHCP) is selected, click Set up PC hotspot if it isn't already set up and click Start relay.

6. Connect your Switch or Switch 2 to the PC Hotspot normally. If your Switch or Switch 2 was already connected, simply turn on and off either Sleep Mode or Airplane Mode (both work).

Manual Mode:

5. Go back to the Play section of GRID0-ofw, make sure Manual IP settings is selected, click Start relay and notice the Switch IP settings it provides you.
6. On your Switch or Switch 2, enter Network Settings, Change Settings on the same network your PC is connected to, and enter the provided IP settings. (Primary DNS can be set to 8.8.8.8 and Secondary DNS can be left blank).

Then just start the relay and play with your friends over LAN!
