Segatools.ini [exclusive] (2025-2027)

High level of customization; lightweight; avoids the need for expensive proprietary hardware.

| Setting | Description | |---------|-------------| | enable= | Set to 1 to enable LED board emulation. |

| Setting | Description | |---------|-------------| | dipsw1= | Emulated DIP switch for Distribution Server. If multiple machines exist on the same LAN, set to 1 on exactly one machine and 0 on all others. | | freeplay= | Set to 1 to enable freeplay mode. This disables the coin slot entirely. Note that some game modes may not allow freeplay. | segatools.ini

The file is typically organized into several key sections that manage how the PC hardware interacts with the arcade game software:

[Emulation]

| Setting (io4) | Description | |---------------|-------------| | mode= | Input API selection. Set to "xinput" for Xbox-compatible gamepads, "dinput" for other devices, or 2 for keyboard. | | test= | Virtual-key code for the Test button (often 0x31 for the 1 key). | | service= | Virtual-key code for the Service button (often 0x32 for the 2 key). | | coin= | Virtual-key code for coin insertion. | | mouse= | Set to 1 to enable mouse lever emulation—essential for games like CHUNITHM that use sliders. | High level of customization; lightweight; avoids the need

This is where you define how you control the game using your keyboard, gamepad, or racing wheel. Settings often use Windows Virtual-Key Codes for mapping.

Add reset_delay=1000 (or higher) in the [jvs] section. Increase the value until the error disappears.

Ensure the amfs folder contains the game's archive files. Use absolute paths (e.g., C:\Games\CHUNITHM\amfs ) to avoid relative path issues. If multiple machines exist on the same LAN,

[Keychip] # Keychip ID (usually 4 hex pairs) id=A0 B1 C2 D3

Because these games expect specific, proprietary arcade hardware (such as JVS I/O boards, Aime IC card readers, and dedicated network billing infrastructures), they will crash or refuse to boot on a normal home PC. segatools.ini intercepts these hardware checks, mapping arcade behaviors to standard PC inputs, file directories, and local network setups. The Architecture of Segatools

| Setting | Description | |---------|-------------| | amfs= | Path to the directory containing the game's main asset files (often ICF1 and ICF2 ). | | option= | Path to the directory containing configuration options (often OPxx or MOV1 , PAR0 , PAR1 , RES0 , RES1 directories). | | appdata= | Path to an empty directory for runtime data. This can be shared across multiple SEGA games. |

Critical for redirecting where the game looks for save data and game options. Ensure these paths point to existing folders relative to the game's executable. Points the game to a custom server for network features. [io3] / [dinput]:
