Hardware Strange problem with Wiimote

[Gan1664]

I have a Bigben Wiimote who was working very well during 6 month.

Now, it works good in the system menu but the hand and the directions are reverted in all homebrew apps (HBC, WiiMC, USBloader, etc...).

I'm on a 4.2 Wii, cIOS38 rev20, DarkCorp 1.1.

Any ideas ?? (I have tried new battery, sync end re sync, etc ...)
