Smash Box and Slippi Netplay


The Melee community now has roll-back netplay! Here's we'll provide instruction on how to set it up and trouble-shoot, especially for our Smash Box users.

Adapter

To play on PC you'll need a GC-to-USB adapter. Luckily, we have an adapter just for that! If you already have a 4-port Mayflash or an official Nintendo adapter, that'll work too. Just ensure that you have both USBs plugged into your PC for the Mayflash adapter when using your Smash Box.

With the adapter, you'll need to download and install Zadig. To properly install, be sure to go to "Options" and select "List All Devices." Ensure your adapter is in Switch/WiiU mode and plugged in, choose "WUP-028" and then install.

 

 

  • GC-to-USB adapter
  • Set to Switch/WiiU mode
  • Zadig downloaded and installed
  • If using Mayflash with a Smash Box, plug both USBs into PC

Slippi

Next you'll need to get the Slippi build of Dolphin. Download page linked right below.

Download from the Slippi page, extract, and open up Dolphin.

 

Now, double-click the text that appear on Dolphin to choose the folder that your Melee iso lives. If successful, Melee and other games you have in that folder should show up in Dolphin's main window. (You can also go to "Options," then "Configuration," then "Path" and add the folder that way.) 

To optimize how the game runs, go to "Options" -> "Graphics Settings." Under the "Display" section, select "Use Fullscreen." This will limit the lag when the game is running. Also, if you want a better looking Melee, go to the "Fullscreen Resolution" option, and choose the best option for your PC.

Finally, start up Melee through Dolphin. Press A to log in, and it should take you to an official Slippi page. Follow the instructions on that page to set up your netplay account.

  • You should be all set to play roll-back netplay Melee!
  • Download, extract, and open Dolphin
  • Choose file path for your Melee iso
  • Set up to use fullscreen, and change your resolution
  • Start up Melee, log in, and set up your account
