RetroArch 2on2 Setup Guide

[chaos]

EDIT 11/14/2020 - This has changed much since the original write-up was done. I updated it to RetroArch version 1.8.8. 

 

This is a guide to setting up 4-way play on RetroArch. Useful for the 2on2 ROM.

The 2on2 ROM for both Genesis and SNES are included with the RetroArch package that you can find on nhl94online.com.

Please make sure you have loaded the ROM at least once before (Load Core->Genesis Plus GX or Snes9x, then Load Content->Start Directory->Genesis or Super Nintendo->2on2 ROM).

The person hosting should have direct connect set up. This will give the smoothest connection for everyone. This also allows you to swap teammates and reset the game if there is a crash while keeping everyone connected.

Both Genesis and SNES will be covered in this guide.

 

Step 1: Set Controls

Load the 2on2 ROM. Once it is running, access the Quick Menu (by going to Command->Menu Toggle on the Menu Bar or pressing F1 key), and go down to "Controls", then select "Port 1 Controls".

 

In the Controls window, change "Device Type", using the left and right arrow keys on your keyboard, to "MD Joypad 3 Button + 4-WayPlay" for Genesis, and leave it as "SNES Joypad" for SNES. Hit backspace, and choose "Port 2 Controls". Set "Device Type" to "MD Joypad 3 Button + 4-WayPlay" for Genesis, and set it to"Multitap" for SNES.

 

 

Step 2: Check 4 Player Setting

Once done with Step 2, you will need to "Restart" the game (Quick Menu->Restart). For Genesis, goto the Game Setup screen and see if you can set the "Players" to "Four" :

 

For SNES, choose your teams and settings, hit Start, and make sure there are 5 stars shown on the "Player Select" screen:

If you are successful, move to Step 4. If not, recheck the Port Control settings.

Step 4: Save Game Remap File

Once you are successful, you can save the Game Remap File, which will save the User Device Types specific to this game. This way you don't need to set it up every time, and you don't need to worry about changing it back when playing normal netplay.

With the game still loaded (don't quit the game, or else the settings above will go back to default!), go to Quick Menu->Controls->Save Game Remap File". A message will pop up that the file has been saved.

 

Now, when you load the 2on2 ROM, it will automatically load the Game Remap File (and your 4-WayPlay/Multitap setup)! This way, you will not have to redo this and undo it every time you decide to play. So, you only need to go through this setup once.

 

Step 5: Start Netplay and Play

Start Netplay as you usually would (Main Menu->Netplay->Host->Start Netplay Host). This can be done before loading the ROM, or after (go to Quick Menu, go back a few times to the Main Menu). Then, once you hosting and the ROM is loaded, have the other players connect to you.

In Genesis, Players 1 and 3 are the Home team, 2 and 4 are the Away team. To switch players, press the "i" key to "leave the game". Then the "i" key should be pressed in the order of players. (Example: If player 2 and 3 "leave the game", and Player 2 wants to be Player 3, Player 3 wants to be Player 2, Player 3 presses "i" key first, then Player 2 presses the "i" key. Now they are swapped.)

*noob alert* so how does the actual connection work, is someone hosting via dc? if so don't you need to set up port forwarding and all that?

Yeah, this is covered in another thread - 

 

 

The host is the only one who needs to have set up port forwarding. Anyone can connect to the host.

So, WTGA ? 

I did these settings for 2on2 and now when I host a normal 1v1 game, I have control for both players. Is this normal ?

Do I have to revert the settings back everytime I wanna play 1v1/2on2 ?

Did you do the "save game remap file" at the end? That's the step that's supposed to revert the change automatically when you play a different ROM.

Yeah. I actually just hosted a 2on2 game and I had control of all 4 skaters...
