Doughston 246dd3a1c6 Hold a Splatoon 3 rematch lobby while either Gamesync session has backfill open 
The 0.8.2 rematch gate read only the secondary session's ebf whenever a
secondary was active. A Salmon Run crew from a friends room holds two
sessions, the room and the job, and the room never opens ebf, so the gate
passed and the host locked the reopened job 2.03 s after Again! in every
room-crew rematch on 2026-10-17. Waiting while either session is open keeps
the lobby for GRID0's lock. Unicorn runs all 16 flag combinations; not yet
tried on hardware.

Setup Guide

The GRID0+ cfw package runs on your modded Switch as a background sysmodule and homebrew app. Follow the steps below to connect to the GRID0+ custom servers.

Requires firmware 22.5.0.

  1. Register a GRID0+ account with the Discord bot (/register). Save the password, you can reset it with /reset-password.
  2. Download the SwitchNet Toolbox from the releases tab and install it on your Switch. (drag and drop the .nro inside the switch folder of your SD card)
  3. If you used Prelude or Nextendo before, open Prelude and switch back to Nintendo first (even if it already says Nintendo mode), reboot, then switch to GRID0+ in the Toolbox. It backs up your hosts folder automatically.
  4. Link the account: System Settings > Users > Add a User > Import from another console > No > Yes > Link Account, then sign in with your GRID0+ account in the browser window.

Then just open the game and play with your friends on GRID0+!
