Introduction

This file describes configuration settings for Segatools that are common to all games.

Keyboard binding settings use Virtual-Key Codes.

[aime]

Controls emulation of the Aime card reader assembly.

enable

Default: 1

Enable Aime card reader assembly emulation. Disable to use a real SEGA Aime reader (COM port number varies by game).

aimePath

Default: DEVICE\aime.txt

Path to a text file containing a classic Aime IC card ID. This does not currently work.

felicaPath

Default: DEVICE\felica.txt

Path to a text file containing a FeliCa e-cash card IDm serial number.

felicaGen

Default: 1

Whether to generate a random FeliCa ID if the file at felicaPath does not exist.

scan

Default: 0x0D (VK_RETURN)

Virtual-key code. If this button is held then the emulated IC card reader emulates an IC card in its proximity. A variety of different IC cards can be emulated; the exact choice of card that is emulated depends on the presence or absence of the configured card ID files.

[amvideo]

Controls the amvideo.dll stub built into Segatools. This is a DLL that is normally present on the SEGA operating system image which is responsible for changing screen resolution and orientation.

enable

Default: 1

Enable stub amvideo.dll. Disable to use a real amvideo.dll build. Note that you must have the correct registry settings installed and you must use the version of amvideo.dll that matches your GPU vendor (since these DLLs make use of vendor-specific APIs).

[clock]

Controls hooks for Windows time-of-day APIs.

timezone

Default: 1

Make the system time zone appear to be JST. SEGA games malfunction in strange ways if the system time zone is not JST. There should not be any reason to disable this hook other than possible implementation bugs, but the option is provided if you need it.

timewarp

Default: 0

Experimental time-of-day warping hook that skips over the hardcoded server maintenance period. Causes an incorrect in-game time-of-day to be reported. Better solutions for this problem exist and this feature will probably be removed soon.

writeable

Default: 0

Allow game to adjust system clock and time zone settings. This should normally be left at 0, but the option is provided if you need it.

[dns]

Controls redirection of network server hostname lookups

default

Default: localhost

Controls hostname of all of the common network services servers, unless overriden by a specific setting below. Most users will only need to change this setting. Also, loopback addresses are specifically checked for and rejected by the games themselves; this needs to be a LAN or WAN IP (or a hostname that resolves to one).

router

Default: Empty string (i.e. use value from default setting)

Overrides the target of the tenporouter.loc and bbrouter.loc hostname lookups.

startup

Default: Empty string (i.e. use value from default setting)

Overrides the target of the naominet.jp host lookup.

billing

Default: Empty string (i.e. use value from default setting)

Overrides the target of the ib.naominet.jp host lookup.

aimedb

Default: Empty string (i.e. use value from default setting)

Overrides the target of the aime.naominet.jp host lookup.

[ds]

Controls emulation of the "DS (Dallas Semiconductor) EEPROM" chip on the AMEX PCIe board. This is a small (32 byte) EEPROM that contains serial number and region code information. It is not normally written to outside of inital factory provisioning of a Sega Nu.

enable

Default: 1

Enable DS EEPROM emulation. Disable to use the DS EEPROM chip on a real AMEX.

region

Default: 1

AMEX Board region code. This appears to be a bit mask?

• 1: Japan
• 2: USA? (Dead code, not used)
• 4: Export
• 8: China

serialNo

Default AAVE-01A99999999

"MAIN ID" serial number. First three characters are hardware series:

• AAV: Nu-series
• AAW: NuSX-series
• ACA: ALLS-series

[eeprom]

Controls emulation of the bulk EEPROM on the AMEX PCIe board. This chip stores status and configuration information.

enable

Default: 1

Enable bulk EEPROM emulation. Disable to use the bulk EEPROM chip on a real AMEX.

path

Default: DEVICE\eeprom.bin

Path to the storage file for EEPROM emulation. This file is automatically created and initialized with a suitable number of zero bytes if it does not already exist.

[gpio]

Configure emulation of the AMEX PCIe GPIO (General Purpose Input Output) controller.

enable

Default: 1

Enable GPIO emulation. Disable to use the GPIO controller on a real AMEX.

sw1

Default 0x70 (VK_F1)

Keyboard binding for Nu chassis SW1 button (alternative Test)

sw2

Default 0x71 (VK_F2)

Keyboard binding for Nu chassis SW2 button (alternative Service)

dipsw1 .. dipsw8

Defaults: 1, 0, 0, 0, 0, 0, 0, 0

Nu chassis DIP switch settings:

• Switch 1: Game-specific, but usually controls the "distribution server" setting. Exactly one arcade machine on a cabinet router must be set to the Server setting.
  • 0: Client
  • 1: Server
• Switch 2,3: Game-specific.
  • Used by Mario&Sonic to configure cabinet ID, possibly other games.
• Switch 4: Screen orientation. Only used by the Nu system startup program.
  • 0: YOKO/Horizontal
  • 1: TATE/Vertical
• Switch 5,6,7: Screen resolution. Only used by the Nu system startup program.
  • 000: No change
  • 100: 640x480
  • 010: 1024x600
  • 110: 1024x768
  • 001: 1280x720
  • 101: 1280x1024
  • 110: 1360x768
  • 111: 1920x1080
• Switch 8: Game-specific. Not used in any shipping game.

[hwmon]

Configure stub implementation of the platform hardware monitor driver. The real implementation of this driver monitors CPU temperatures by reading from Intel Model Specific Registers, which is an action that is only permitted from kernel mode.

enable

Default 1

Enable hwmon emulation. Disable to use the real hwmon driver.

[jvs]

Configure emulation of the AMEX PCIe JVS controller (not IO board!)

enable

Default 1

Enable JVS port emulation. Disable to use the JVS port on a real AMEX.

[keychip]

Configure keychip emulation.

enable

Enable keychip emulation. Disable to use a real keychip.

id

Default: A69E-01A88888888

Keychip serial number. Keychip serials observed in the wild follow this pattern: A6xE-01Ayyyyyyyy.

gameId

Default: (Varies depending on game)

Override the game's four-character model code. Changing this from the game's expected value will probably just cause a system error.

platformId

Default: (Varies depending on game)

Override the game's four-character platform code (e.g. AAV2 for Nu 2). This is actually supposed to be a separate three-character platformId and integer modelType setting, but they are combined here for convenience. Valid values include:

• AAV0: Nu 1 (Project DIVA)
• AAV1: Nu 1.1 (Chunithm)
• AAV2: Nu 2 (Initial D Zero)
• AAW0: NuSX 1
• AAW1: NuSX 1.1
• ACA0: ALLS UX
• ACA1: ALLS HX
• ACA2: ALLS HX2

region

Default: 1

Override the keychip's region code. Most games seem to pay attention to the DS EEPROM region code and not the keychip region code, and this seems to be a bit mask that controls which Nu PCB region codes this keychip is authorized for. So it probably only affects the system software and not the game software. Bit values are:

• 1: JPN: Japan
• 2: USA (unused)
• 3: EXP: Export (for Asian markets)
• 4: CHS: China (Simplified Chinese?)

systemFlag

Default: 0x64

An 8-bit bitfield of unclear meaning. The least significant bit indicates a developer dongle, I think? Changing this doesn't seem to have any effect on anything other than Project DIVA.

Other values observed in the wild:

• 0x04: SDCH, SDCA
• 0x20: SDCA

subnet

Default 192.168.100.0

The LAN IP range that the game will expect. The prefix length is hardcoded into the game program: for some games this is /24, for others it is /20.

[netenv]

Configure network environment virtualization. This module helps bypass various restrictions placed upon the game's LAN environment.

enable

Default 1

Enable network environment virtualization. You may need to disable this if you want to do any head-to-head play on your LAN.

Note: The virtualized LAN IP range is taken from the emulated keychip's subnet setting.

addrSuffix

Default: 11

The final octet of the local host's IP address on the virtualized subnet (so, if the keychip subnet is 192.168.32.0 and this value is set to 11, then the local host's virtualized LAN IP is 192.168.32.11).

routerSuffix

Default: 1

The final octet of the default gateway's IP address on the virtualized subnet.

macAddr

Default: 01:02:03:04:05:06

The MAC address of the virtualized Ethernet adapter. The exact value shouldn't ever matter.

[pcbid]

Configure Windows host name virtualization. The ALLS-series platform no longer has an AMEX board, so the MAIN ID serial number is stored in the Windows hostname.

enable

Default: 1

Enable Windows host name virtualization. This is only needed for ALLS-platform games (since the ALLS lacks an AMEX and therefore has no DS EEPROM, so it needs another way to store the PCB serial), but it does no harm on games that run on earlier hardware.

serialNo

Default: ACAE01A99999999

Set the Windows host name. This should be an ALLS MAIN ID, without the hyphen (which is not a valid character in a Windows host name).

[sram]

Configure emulation of the AMEX PCIe battery-backed SRAM. This stores bookkeeping state and settings. This file is automatically created and initialized with a suitable number of zero bytes if it does not already exist.

enable

Default 1

Enable SRAM emulation. Disable to use the SRAM on a real AMEX.

path

Default DEVICE\sram.bin

Path to the storage file for SRAM emulation.

[vfs]

Configure Windows path redirection hooks.

enable

Default: 1

Enable path redirection.

amfs

Default: Empty string (causes a startup error)

Configure the location of the SEGA AMFS volume. Stored on the E partition on real hardware.

appdata

Default: Empty string (causes a startup error)

Configure the location of the SEGA "APPDATA" volume (nothing to do with the Windows user's %APPDATA% directory). Stored on the Y partition on real hardware.

option

Default: Empty string

Configure the location of the "Option" data mount point. This mount point is optional (hence the name, probably) and contains directories which contain minor over-the-air content updates.
