This firmware emulates arcade IO. As such, segatools' emulation should be disabled, by adding the following lines:
```ini
[slider]
enable=0
[io4]
enable=0
```
Ensure no other `[slider]` section exists in the file (or if it does, set `enable=0` there instead).
The slider **MUST** be assigned to port `COM1`. To do this:
- Go to `Devices and Printers` in control panel
- Double click `TASOLLER`
- In the `Hardware` tab, double click `USB Serial Device`
- If this already reads `USB Serial Device (COM1)` nothing needs done
- Click `Change settings`
- Go to `Port Settings` -> `Advanced...`
- Under the dropdown for `COM Port Number:` select `COM1`
If `COM1` is already in use, check what device it is assigned to in Device Manager under `Ports (COM & LPT)`. You may need to enable `View` -> `Show hidden devices`.
Pre-chusan Chunithm uses IO3. This firmware does not (and unfortunately cannot) support IO3. It is recommended to enable the HID keyboard mode, and continue to use keyboard input for IRs.
To enter the system test menu, double-tap FN2. This will mirror the on-screen controls, and additionally adds controls for the TEST and SERVICE buttons on a real cabinet. Double-tap FN2 again to leave this mode on the controller (note that this is not synced with the game exiting the menu!).
