## Netplay

By default **Netplay** is ***disabled***, <br>
to enable it, add the following:

```js
// ID in your website, required for netplay. Each game in your site should have a different ID
EJS_gameID = 1;
```

<br>

by default, the netplay server url will be `emuserver.emulatorjs.ga`, but to default to the default `ws.emulatorjs.com` server add the following line

```js
EJS_oldEJSNetplayServer = true;
```

<br>

EJS_startOnLoaded = true;
```

*For audio to play the user still* <br>

EJS_paths = {
    'fileName' : '/somepath',
    'emulator.js' : 'https://example.com/emulator.js',

## Using MAME

To use the **MAME** system you will have to add:

```js
EJS_core = 'mame';
EJS_mameCore = '' // mame core options (example: '4|0')
```

to your code.

Set the mame core value to the mame core number ( `1` - `6` ) + `|` + save states supported ( `0` or `1` )
