Data and game setup

  1. Get the data
  2. Ensure the game files are not marked read-only
  3. Start up your favorite ALLNET server implementation in the background. Whether or not you plan to save your scores the game must be "blessed" by a server at least once, otherwise there will be a spinner on the title screen forever and you will be unable to start a credit
  4. The data releases have the following structure:
  • app/: Game data
  • option/: Addon data
  • amfs/: Metadata
  1. Unpack segatools to the app/bin directory
  2. Create an appdata foder (this isn't Windows APPDATA) in the data release next to app/, option/ and amfs/
  3. In the [vfs] section of app/bin/segatools.ini set the paths for the folders:
[vfs]
amfs=../../amfs
appdata=../../appdata
option=../../option
  1. In the [dns] section, set default= to your computer's hostname or LAN IP. Do not put 127.0.0.1 here, the game specifically checks for and rejects loopback addresses. This setting controls the address of the network services server
  2. Right click start.bat in app/bin and run it as Administrator. I think you need to run it as admin at least once, but once you have done that you can run the game as a regular user
  3. A sequence of several start-up screens will be displayed. You should also see a bunch of debug output in a command line window; if you're seeing hex dumps here then that's a good sign. There will eventually be a screen with a red error message about LEDs. This is being displayed because Segatools does not currently emulate the cabinet's RGB LED strips
  4. Press 1 to go to the operator menu. Use either Test/Service or the touch bar to navigate the options
  5. Select ゲーム設定 (Game settings)
  6. Select 配信サーバー設定 (Distribution server setting)
  7. Set this setting to サーバー　(Server)
  8. Select 筐体グループ設定 (Cabinet group setting)
  9. Set this setting to OFF
  10. If desired, you can also set 音楽選択時間設定 (Music selection time setting) to 99 or whatever
  11. Select 終了 (Finish)
  12. There will be a centered prompt notifying you that a restart is necessary to put your new settings into effect. Confirm both prompts. The game will now exit

This setting has nothing to do with the game's central network services, it describes the role that the cabinet has on the shop LAN. To be exact, every networked group of SEGA cabinets (one cabinet is still a group) must have exactly one cabinet designated as the "Distribution Server" and all the others configured as "Clients". The clients will search for a distribution server on their inter-cabinet LAN: they will not finish starting up until they find one.

Normally the client/server setting is controlled by DIP switch 1 on the Nu PCB chassis. However, for some reason this is controlled from the operator menu in Chunithm. And the default setting after NVRAM reset is Client mode.

  • Start the game up again, then dismiss the LED error message using the touch strip. You should see a title screen with a red glow along the bottom (or, if you were less lucky, a red banner or a spinner that doesn't go away).
  • Press 2 or 3 a few times to add some credits, then hold the Enter key for a few seconds to scan a card and start a credit. A random card ID will be written to DEVICE\felica.txt the first time you do this.

FAQ

Where is the Free Play setting?

In the SEGA Nu system supervisor program, which is not included in this release. A command-line tool to change this setting will be provided in a future release of Segatools.

The network test screen shows a bunch of BAD checks and (either a red RTC error screen or an infinite spinner on the title screen) appears which I can't get past

This means that the game's ALLNET client software failed to start up. The ISP domain squatting thing is a common cause for this problem, but unfortunately there are a large number of other possibilities. Try uncommenting the chuniApp.exe=chunispike.txt line in segatools.ini to enable the internal ALLNET debug log; this may possibly yield some clues.

What does the red "本日のプレイ受付は終了しました" text on the title screen mean?

"Play acceptance has ended for today". Basically it means that it's outside legal operating hours for Japanese arcades right now. Hopefully somebody can come up with a hex edit to bypass that message but for now you'll need to change your PC's clock or something.

How do I play courses?

This requires additional server support which might not be implemented currently.

How do I unlock a character other than the penguin?

Pick any map other than the default. You will see characters available as potential rewards for those maps.
