How to use a adress from Dolphin memory engine ?

[Schneitizel S. Sekai]

Hi all !

I use Dolphin Memory Engine to create a cheatcode for The Sims (And after The Sims 2 and Bustin out)
I have two addresses, 817B5AC4 and 817B5AC8 that work, I would like to put them in Dolphin but in AR codes or Gecko Codes, when I put
817b5ac4 00000000
817b5ac8 00000000
Nothing happens, nothing works...

How can I fix this?
Thank you in advance
