 Pop'n Controllers report as digital controllers (ID byte 41h), but the left, right, and down d-pad controls are not connected to any physical buttons and are always reported as pressed (in the first transferred button byte, bits 5-7 are always 0). Pop'n Music games check these bits to determine if a Pop'n Controller is connected and will change the in-game controls accordingly if so.

+- The workings of Densha de Go! PSX controllers have been extensively researched in the [ddgo-controller-docs](https://github.com/MarcRiera/ddgo-controller-docs) repo.
+- The Jet de Go! PSX controller comes in gray and black color.
+  It seems to work the same as an analog controller and supports vibration.
+  The steering wheel is mapped to the left stick (wheel rotation as horizontal, wheel raise/lower as vertical axis).
+  The thrust throttle seems mapped to the right stick Y-axis full range (so half throttle matches vertically centered right stick).

+Comes in an orange variant (TW-20001) and a blue variant (TW-20002).
+Was available for purchase as a standalone controller or as a bundle with Happy Jogging in Hawaii.
+Requires an analog controller to be connected to the stepper in order to work.
+The stepper forces the analog controller to switch to analog mode.
+With some (cheap?) third-party Playstation controllers, this might actually result in permanently activating the controller's rumble.
+The stepper overwrites the left stick X-axis values with the position of the stepper pedals:
+- Left stepper pedal fully down equals to left stick fully to left
+- Right stepper pedal fully down equals to left stick fully to right
+- Left and right stepper pedal equal height matches left stick horizontally centered
+Further details unknown.
