# Setting Up Chunithm for Cabinet-to-Cabinet Play (Multiplayer) over the Internet

!!! danger "You are most likely to have success with Multiplayer when all users are using the SAME data and options, from the same sources. Verify that each person can run the game normally before attempting to network them together."

!!! tip ""

	- Chunithm expects the cabinets to be using specific IP addresses, 192.168.139.**11/12/13/14**
	- To achieve this over the internet, we can use SoftEther VPN. Refer to the [Setting Up SoftEther VPN Guide](../../extras/softether.md) for more information.

### Configuring segatools.ini & Game Assignments

!!! tip "segatools.ini"

	```
	[netnev]
	enable=1
	addrSuffix= last 2 digits of your SoftEther IP

	[keychip]
	enable=1
	subnet=192.168.139.0
	id=(Everyone needs a seperate keychip. If you play on a remote network, chances are you already have your own keychip. If not, you can use the example keychips below.)
	;example keychips: A61E-01D02321145 ; A61E-01A30831145 ; A61E-01E38091145 ; A61E-01E46241145

	[system]
	dipsw1=1
	;Set this to 1 on the Server machine, and 0 on all other client machines.
	;If your game gets stuck on "Checking for Dist Server", try setting this to 1 on all machines and continue following the steps.
	```

!!! tip "GAME ASSIGNMENTS"

	- After saving your segatools.ini, launch the game and go into the Service Menu > and go to ```GAME ASSIGNMENTS```.
