chaos 149 Report post Posted February 8 This is a guide to setting up 4-way play on RetroArch. Useful for the 2on2 ROM. Link to Genesis 2on2 ROM - 2on2 Update Thread Please make sure you have loaded the ROM at least once before (Load Core->Genesis Plus GX, then Load Content->2on2 ROM). I suggest placing the ROM in your ROMs folder inside the RetroArch-32 folder (or wherever else you decide to keep your ROMs). 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. So far, only confirmed this on Genesis GPGX core (prob should work in a similar fashion for Snes9x core): Step 1: Set Max Users to 4 Start RetroArch. Go to Settings->Input. Set Max Users to 4 (this is safe to leave this way, you don't have to change this back). Exit and restart RetroArch. Step 2: 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. In the Controls window, change "User 1 Device Type" and "User 2 Device Type" to "MD Joypad 3 Button + 4-WayPlay". Make sure "User 3 Device Type" and "User 4 Device Type" are set to "RetroPad" (this should be default setting). Step 3: Set to Four Player Once done with Step 2, you will need to "Restart" the game (Quick Menu->Restart). Go to the Game Setup screen and see if you can set the Players to "Four": 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. With the game loaded, 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 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->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). I would suggest telling the players to connect after you set the Players to "Four" in the Game Setup screen. 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.) 1 1 Share this post Link to post Share on other sites
