Hacking Homebrew Connecting Controller Pro U to Homebrew Applications

[JEEJEE]

I have a Controller Pro U controller (it looks like Classic Controller Pro, but with Snes layout) and I'm using it with my Wii. This controller can be used as a Wiimote or Classic Controller. Everything works fine with Wii games (both Wiimote and Classic Controller modes works)

However, when I boot up Snes9x GX (or any Homebrew application), only the Wiimote mode works. For some reason, Homebrew applications doesn't recognize this controller as CC, even if they support Classic Controllers.

Is there any workaround?

NOTE: This controller is NOT Wii U Pro Controller, it's some third party controller made for Wii

I have tested following:
Mario Kart Wii (CC Works)
Smash Bros. Brawl (CC Works)
Snes9x GX/RX/TX (CC doesn't work)
