Gamecube controller with Brawl

[quality]

Hi. So i recently got this MayFlash adapter for my pc, which basically lets you connect a gamecube controller to your pc.
So i went into the configuration tab in Dolphin to set up the buttons and everything goes well, all buttons respond in the Dolphin UI.

The problem is when im trying to use this setup in Super smash bros Brawl, all the buttons works perfectly fine, except the trigger ones(L&R),
which doesn't respond at all when you press em. So I tried the same setup in Melee, and there the trigger buttons works just like they should.

What can the issue be here, why won't the trigger buttons work in Brawl but in Melee?

This L R issue has been over done around here. I do not memorize the solution but searching will reveal your answer.

did you set L, R, analog-L and analog-R ?

I set the L and R to when the triggers are fully pressed down now and it seems to be working! Which is weird becuase im pretty sure i tried it before.
Was thinking Brawl was using L/R analog aswell, like in Melee, but i guess not. Anyways, thanks for your replies!

Actauly ALL games use trigger, and then some games do make use of analog
