Setting up

1. Get the game ISO.
   • If one of you isn’t using a 1:1 perfect rip of the ISO, there may be desync issues.
   • You may want to ask around the GNT Discord server as to where you can find it.
2. Download Dolphin version 5.0-321.
   • Other versions of Dolphin will work, but both you and your opponent must use the same version.
   • Alternatively, you could use the Kuroha Saenoki Translation Dolphin Build with Fixed AR Codes for Netplay, which should also work fine when playing other 5.0-321 Dolphin builds.
3. Set up your game controller by selecting "Controllers."
   • If you would like to use a GameCube controller, use this info from the official Dolphin Wiki.
4. Hit "Browse" and select the folder that GNT4 is in.
   • GNT4 should now show up in your game list on the main Dolphin menu.
5. Right click on the GNT4 banner in the games list and select "Properties">"AR codes" and make sure "Everything Unlocked" is checked.
   • If you’re playing GNT4 Remastered, the rebalance mod, you don’t need to do this. The mod unlocks everything by default.
6. Go to "Config."
   • Under "General," make sure "Enable Cheats" is selected.
   • Under "GameCube," make sure "Nothing" is selected for the memory cards.
7. Give the game a test play to make sure the unlock code worked, your controller is working, and you hit a constant 60FPS.

Using Netplay

1. To begin Netplay, go to "Tools">"Netplay" and in the top-left, select "Traversal Server."
2. If you are hosting, you will get a "Room ID" for your opponent to connect to.
   • If not, politely wait for your opponent to send you their "Host Code."
3. The pad buffer should be the ping divided by 8, rounded up.
   • Every 4 pad buffer is 1 frame.
   • For versions of Dolphin at base 5.0 and older, divide by 15.
   • If the game is stuttering too much, increase the pad buffer.
4. Remember that you’ll have to change the GNT4 settings from the in-game settings menu every time you boot the game, since memory cards are disabled.
   • Recommended rounds is 3/5, recommended timer is 90 seconds.
5. If the chat window says there was a possible desync, confirm with your opponent that you’re both seeing the same thing when there’s some downtime.
   • If you are not both seeing the same thing, a desync happened, and you’ll have to restart the session.
6. End all matches with a super.
   • Rage quit if a match is ended with a super.
