Troubleshooting¶

Codes and messages as segatools and the games actually emit them. The AM Daemon console window is the source for most of these — read it before changing anything.

Before you start¶

Three things cause most "segatools issues" that aren't in this list:

Games on a non-C drive. Anything installed on E:\ launches with errors for no clear reason. Either move it to C:\, or map a drive letter: subst X: "E:\Games\SDDT\" and launch from X:\.
Your Windows username equals your PC name. Causes CreateFileMappingW failed in SharedMemory.cpp. Rename one of them.
A stale segatools. Several of these are fixed in current releases. Check the release tag before working around an error.

Setup problems¶

Symptom	Cause and fix
Game won't boot, no coin/test/service buttons register, `unitIndex is out of range` in `Aime.cpp`	OpenSSL SHA crash bug on Intel 10th gen or newer. Fixed in segatools 2025-11-04 — update. The old `OPENSSL_ia32cap` workaround is deprecated.
Stuck on "checking distribution server" (配信サーバーチェック中)	`dipsw1=1` in `segatools.ini`, or `dipsw1=0` for `SDED`.
Stuck on "settings synchronizing" (設定同期中)	Test Menu (F1) → GAME ASSIGNMENTS → CABINET-TO-CABINET PLAY → OFF. Or leave it on and set the Server cabinet to REFERENCE MACHINE.
Version wrong, or shows only 0.00	`amfs=` path wrong, or the folder lacks `ICF1` and `ICF2` with no file extension.
Option data missing	`option=` path wrong, or the option folder isn't an `Axxx` schema folder.
Coin input dead	`amdaemon.exe` has crashed, or the `coin=` key binding in `segatools.ini` is wrong.
Game looks cut off	Wrong native mode for the code — see Game codes.
`IP Address: BAD`	`netenv` disabled in `segatools.ini`. If you need it off, your real IP and subnet have to match what the game expects.
`DNS: BAD`	`mobirouter.loc` or `dslrouter.loc` resolved for real. segatools stubs these; your DNS server is catching them first.
Windows 11: "An assertion failure has occurred" in `MSCTF.dll`	The shell handwriting experiment. `vivetool /disable /id:41799415`, then reboot.

In-game errors¶

Code	Meaning
0000	Bad dump. Get a better one.
0032	Usually DHCP mismatch — the game wants a static IP. Add the fix to `config_hook.json`.
0800	"Cannot get accounting info" spamming in AM Daemon — usually a non-ASCII Windows username. segatools writes it under `C:\Users\<username>\temp`.
3101 / 3102	Main device init failed — the Chusan/CHUNITHM controller isn't detected. Check chuniio, try another USB port.
320X	You touched the CHUNITHM Air Sensors.
3400 / 3401	Monitor error — refresh rate must match the game's native mode exactly.
4105	Check AM Daemon for a "Runtime Error Exception" — the real message is in the AM Daemon section below.
6401	I/O board not connected. Restart, and check you aren't out of CPU.
6501	Aime reader not found. Enable the reader emulation in `segatools.ini`.
6503	Failed to read Aime card — needs a working ALL.Net connection.
6509	Aime card has been banned.
8114	ALL.Net system error (RTC). Update segatools, delete `C:\Users\<you>\temp` if present, and be connected to a server on first boot. With no server, set `allnet_accounting: false` in `config_hook.json`.
0919	Disable DVD drives. Update segatools and confirm it logs `DVD: hook enabled.` at startup, else disable the drive.
0949	Keychip removed. Update segatools, or create a new TXT and rename it `first_ar.conf` in `C:\Users\<you>\temp`.

AM Daemon errors¶

Message	Cause
`ampdGd1232a01aInit(). ErrCode -4`	Invalid VFD port. Update segatools or match the port in `config*.json`.
`amAppImageInit(). ErrCode -5`	`amfs` path too long. Newer AM daemon requires the full path (`C:\Games\SDDT\amfs`) under 16 characters.
`RegCreateKeyExW(). ErrorCode -5`	Can't write the registry without admin. Update segatools or run `launch.bat` as admin.
`amSysFileInitEx(). ErrCode -5`	Can't write `sysfile.dat` in the amfs folder — check read/write permissions.
`amGfetcherInit(). ErrCode -1`	`ICF1`/`ICF2` missing or wrong game. Get the ICF matching your code from the SEGAguide packages.

CHUNITHM specifics¶

Full detail on the SDHD page. The short list: JST lockout 01:30–07:00, CVT 120fps does not work, cab-2-cab wants 192.168.139.0 with Server .11 and satellites .12/.13/.14, and the red 本日のプレイ受付は終了しました banner just means you're outside Japanese operating hours.
