We already support Action Replay codes, you can manage them in each game, by doing right clicking > properties > AR Code (but you seem to already know that :p)
Btw, you also have to check "Enable Cheats" in the Dolphin's Config for the cheats to work, and eventually, you can toggle any cheat while in-game by using Tools > AR Code Manager.
Is that what you were looking for ?
