+## Controllers - Taiko Controllers (Tatacon)
+Drum controllers made by Namco and used by the Taiko no Tatsujin series on the
+PS2 (but compatible with the PS1, even though no PS1 Taiko game was ever made).
+These controllers behave like standard digital pads (ID 41h) and contain four
+hit sensors mapped to the following buttons:<br/>
+
+| Sensor             | Button     | Bit |
+| :----------------- | :--------- | --: |

+| Left don (center)  | D-pad left |   7 |
+| Right don (center) | Circle     |  13 |

+Dedicated start and select buttons are also present. Unlike Pop'n Controllers,
+no additional buttons are hardcoded to be always pressed.<br/>
