Do all Gecko Codes work with dolphin?

[gondracorn]

I am playing Pokemon Battle Revolution PAL for Wii, but I'm facing a problem

Some of the already established gecko codes for the game are not executing at all.

For instance,

P2 Pokemon 1 Hit Points Modifier
48000000 8047941C

DE000000 90009340
120000A6 00000001
E0000000 80008000

Is this normal behavior for dolphin?
