Question DK Bongos Identification Mystery

[paddle0]

Happy Holidays!

Donkey Konga graphically represents whether you have DK Bongos or a GameCube controller attached, and varies its menu control scheme accordingly.

Given that DK Bongos and the GameCube controller both provide the same device ID (0x0900) to the console, does anyone have any idea how Donkey Konga "knows" DK Bongos are attached?

I'd like to build my own bongos, et cetera, but short of cannibalizing the control board from actual DK Bongos, I'm not sure how to persuade Donkey Konga it's corresponding with them.

I found this pull request for the Dolphin GameCube emulator:

HW: DK Bongos actual fix by jordan-woyak · Pull Request #7659 · dolphin-emu/dolphin

I promise you that DK Bongos work now.

It held the answer. Basically, if you zero-out the first 16 bits of the GameCube report (including something called PAD_USE_ORIGIN), Donkey Konga behaves as though DK Bongos are connected. Kooky
