I followed an older post to add Dolphin as an emulator, but I have since learned that the format of that particular recommended config file was seemingly out of date. (appScan vs gameScan etc). This is the current config I have setup for enabling the Dolphin emulator:

    {
      "gameType": "wii",
      "displayGameType": "Wii",
      "enable": true,
      "emulator": "Dolphin",
      "gameScan": {
        "type": "directory",
        "dir": "[[gamesPath]]\\wii",
        "ext": [ 
          "iso",
          "wbfs",
          "ciso",
          "gcz",
          "rvz" 
        ]
      },
      "assetScan": {
        "dir": "[[assetsPath]]\\wii"
      },
      "launch": {
        "target": "[[emulatorsPath]]\\Dolphin-x64\\Dolphin.exe",
        "params": [
          "-b",
          "-e",
          "[[gameConfig.filePath]]"
          ]
      },
      "process": {
        "type": "parent",
        "onLaunchFailFocusApp": "Dolphin.exe",
        "isWindowedBorderless": false
      }
    },

When I try to launch a game I am getting this error:
The specified file: ""C:/Users/Polycade/AppData/Roaming/polycade/games/wii/Luigis Mansion.iso"" does not exist.

At first glance the double quotes seems to be the issue, but I don't think I have any control in the config file in manipulating that. Please help.... thank you!
