 +Data is stored in little-endian order.
 +
 +When multiple regions exist for a given information (for example, board info), the first region with a correct CRC16 is selected.
 +
 +
 +===== Board info =====
 +
 +Bit 0-3 of the board info value are the main version, while bit 4-7 are the sub version.
 +
 +Main version:
 +  * 0 = DK1
 +  * 1 = EP_DK2
 +  * 2 = DP1
 +  * 3 = DP2
 +  * 4 = DK3
 +  * 5 = DK4
 +  * 6 = DP3
 +  * 7 = DK5
 +  * 8 = DP4
 +  * 9 = DKMP
 +  * 10 = DP5
 +  * 11 = MASS
 +  * 12 = DKMP2
 +  * 13 = DRC_I
 +
 +Sub version:
 +  * 0 = DK1_EP_DK2
 +  * 1 = DP1_DK3
 +  * 2 = DK4
 +  * 3 = DP3
 +  * 4 = DK5
 +  * 5 = DP4
 +  * 6 = DKMP
 +  * 7 = DP5
 +  * 8 = MASS
 +  * 9 = DKMP2
 +  * 10 = DRC_I
 +
 +
 +===== Region info =====
 +
 +  * 0 = Japan
 +  * 1 = North America
 +  * 2 = Europe
 +  * 3 = China

 +  * 5 = Taiwan
 +  * 6 = Australia
 +
 +
 +===== Board config =====
 +
 +Value is 0x15 for retail boards.
 +
 +If bit0-1 are any value other than 1, the gamepad will enter service mode upon boot.
 +
 +
 +===== Language =====
 +
 +(0-3 = America, 4-11 = Europe)
 +
 +  * 0 = English 
 +  * 1 = French

 +  * 12 = Japanese
 +  * 13 = Chinese (simplified)
 +  * 14 = Korean
 +  * 15 = Chinese (traditional)
 +
 +
 +===== Volume calibration =====
 +
 +^ Offset ^ Length ^ Description ^
 +| 0x00   | 1      | Minimum volume |
 +| 0x01   | 1      | Maximum volume |
 +
 +The minimum and maximum values are used to cap the reading from the volume slider within an acceptable range.
 +
 +TODO: detail how that reading is converted to the final volume setting passed to the audio amplifier
 +
 +
 +===== Gyroscope calibration =====
 +
 +^ Offset ^ Length ^ Description ^
 +| 0x00   | 3      | Zero X |
 +| 0x03   | 3      | Zero Y |
 +| 0x06   | 3      | Zero Z |
 +| 0x09   | 3      | Rotation X |
 +| 0x0C   | 3      | Rotation Y |
 +| 0x0F   | 3      | Rotation Z |
 +| 0x12   | 1      | Speed |

 +| 0x0C   | 2      | Point 2 raw X |
 +| 0x0E   | 2      | Point 2 raw Y |
 +
 +Raw coordinates are 12-bit TSC readings, while screen coordinates are their corresponding values in pixels.
 +
 +Observed screen coordinates are: 53,30 802,451
 +
 +
 +===== LCD brightness levels =====
 +
 +^ Offset ^ Length ^ Description ^
