Gaming pokemon xd, controller goes up

[migles]

i am trying to play pokemon xd, but when i try to walk down, the character goes up...
this issue is weird, since if i slowly tilt the analogic down, character goes down, but if i press the stick more than halfway, the character goes up

it does this in both analogic sticks, the D PAD is working fine..

this also happens on the menus...

i am using a backup (verified hash) and this happens in both dios mios and nintendont

i am using a gamecube controller.., tried both wiiflow and cfg

i also tried to use gamecube combination to reset the analogics, i even tryed to force a position, but doesnt fix the problem (it makes even worse lol)

more weird is, if i use a usb controller with nintendon't it works propertly...
all other games work fine...
