 2. Launch the batch file and the game should open. Ensure you have the correct patched file(s) for the functionality you want to unlock. By default, the game will be capable of running in 'Free Play' mode (activate through the test configuration page). This allows for some gameplay (play up to a certain amount of songs per session, not all songs are unlocked). The machine *can* scan cards if a user has them. From my understanding, it doesn't need a network to do this. 
 
 ### Online Mode (currently being worked on)
+
+For online mode, you will need some more files (which I don't believe are easy to get via the site you should not go to). You will have to ask around for the download, or eventually I'll add a download link here. 
+
+1. Make a `D:\` drive and directory to have the following file tree:
+
+```
+(Assume this is under the `D:\` root)
+├── system
+│   ├── CmdFile
+│   │   └── log
+│   │       └── Log.txt
+│   ├── DUA
+│   │   ├── data
+│   │   ├── decrypt
+│   │   ├── download
+│   │   ├── event
+│   │   ├── news
+│   │   │   ├── 1524476664.png
+│   │   │   └── 1554282603.png
+│   │   ├── unpack
+│   │   └── work
+│   ├── option.txt
+│   ├── Service
+│   │   └── NesysService.exe
+│   └── update.log
+```
+
+You can ignore the files (except the exe). Everything should be created later.
+
+2. Edit your arcade machine's hosts file:
+>Usually under:
+`C:\Windows\System32\drivers\etc\hosts`
+```
+localhost cert.nesys.jp
+localhost cert3.nesys.jp
+localhost data.nesys.jp
+localhost proxy.nesys.jp
+localhost nesys.taito.co.jp
+localhost fjm170920zero.nesica.net
+```
