 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
+  * 4 = South Korea
+  * 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
+  * 2 = Spanish
+  * 3 = Portuguese

+  * 10 = German
+  * 11 = Russian
+  * 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 |
+===== Accelerometer calibration =====
+^ Offset ^ Length ^ Description ^
+| 0x00   | 2      | 0G X |
+| 0x02   | 2      | 0G Y |
+| 0x04   | 2      | 0G Z |
+| 0x06   | 2      | 1G X |
+| 0x08   | 2      | 1G Y |
+| 0x0A   | 2      | 1G Z |
+===== Touchscreen calibration =====
+^ Offset ^ Length ^ Description ^
+| 0x00   | 2      | Point 1 screen X |
+| 0x02   | 2      | Point 1 screen Y |
+| 0x04   | 2      | Point 2 screen X |

+| 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 ^
+| 0x00   | 1      | Level 0 brightness level (setting A) |
+| 0x01   | 1      | Level 0 frequency (setting B) |
+| 0x02   | 1      | Level 1 brightness level |
