Tap FN1 to insert a coin. FN2 is currently unbound.
### Configuration
Hold FN1 for configuration:
While holding FN1, the following configuration options are available:
- Pad 1/2 (cell 0): Left tower colour
- Pad 3/4 (cell 1): Ground colour
- Pad 5/6 (cell 2): Ground colour when pressed, and separator colour
- Pad 7/8 (cell 3): Right tower colour
- Pad 9/10 (cell 4): No function
- Pad 11/12 (cell 5): Toggle rainbow effect on/off
- Pad 13/14 (cell 6): Increase/decrease ground brightness
- Pad 15/16 (cell 7): Increase/decrease tower brightness
- Pad 17/18 (cell 8): No function
- Pad 19/20 (cell 9): System volume up/down
- Pad 21/22 (cell 10): Holds Enter for 5 seconds (insert Aime card)
- Pad 23/24 (cell 11): No function
- Pad 25/26 (cell 12): Increase/decrease sensitivity
- Pad 27/28 (cell 13): No function
- Pad 29/30 (cell 14): No function
- Pad 31/32 (cell 15): Toggle HID keyboard mode

※ "Insert card" will hold the Enter key for 5 seconds
### Test menu
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!).
Cell 6 and 7 are the TEST button, and cell 8 and 9 are the SERVICE button.
![](./docs/Graphic_Slider_Test.png)
To access the TEST and SERVICE buttons without entering the test menu, hold FN2 instead.

## Keyboard Mapping
When the HID keyboard is enabled, the following mapping (UMIGURI defaults) is used:
```
I8U7Y6T5R4E3W2Q1
9KMJNHBGVFCDXSZA
```

with the airs mapped as `0OLP,.`.

Note that our custom firmware is compiled using GCC rather than ARMC5. Our linkerscript is not configured to place any initialisation code after the vectors, and as such this protection mechanism would be likely to cause random crashes rather than a complete inability to execute the firmware.
Rather than implement this as a post-processing step after compiling firmware, our linkerscript is configured to pad C0~CF with nulls.
Rather than implement this as a post-processing step after compiling firmware, our linkerscript is configured to place the compile timestamp within this region, and we account for the DRM modifications when comparing timestamps.
