Wii games don't have much known action replay codes. I and others are now beginning to find them using Dolphin's new 'Cheat Search' function.

Memory editing, in short, involves searching for the values (health, lives, coins, points) that you want to edit, then changing or freezing them. This tutorial used to use Cheat Engine, but an awesome fella implemented a Cheat Search function in one revision, and I and others have improved on it in one way or another.[/color]
If you're seeking to cheat in a Gamecube game, chances are that cheats are already loaded. Right click on the game in the Dolphin window, click on 'Properties'. Go to the 'AR Codes' tab. Choose the codes you want, and start up the game. That's it.
Unfortunately, only a few AR codes are known for Wii games. The following method will teach you how to generate AR codes for Wii (or gamecube) games.
Start the game
Boot into the game you want to find AR codes for.
Open the Cheat Search
This is found in Tools > Cheats Manager. Then go to the Cheat Search tab.
Initialize your target Value
If you're targeting bullets, get into the game so you can see your ammo remaining. If you're targeting health, get into the game and see your health.
Find the inital values
Note: While searching, the value can change (e.g., you're looking for health, and while searching, you get hurt.) This will throw off the value. If you think the value will change during search, pause emulation.
At first, click 'New Scan'. Change the dropdown from 'Unknown' to 'Equal'. In the box, type in the value you're looking for.
Narrow it down
Fire a bullet, get hurt, whatever it takes to change the value. Once the value is changed, type the new value, and click 'Next Scan'.
Found it!
Once you find your code (SHOULD ONLY BE ONE, very rarely, you will see two codes), click 'Create AR Code'.
WRITE DOWN THE AR CODE GENERATED. At this stage, Dolphin's cheat manger has a bug and doesn't always properly save the code generated.
Re-Enter the code when you stop the game
Put your code that you've written down into the config for the game. It's that simple.
Bonus: I only have a FEW tries to get the value, and I'm left with a LARGE number of values even after narrowing it down.
You can use save states to help. Save a state where the target number is high. Search, narrow it down. When you run out, just load the state, and continue searching and narrowing it down. You will eventually find the code this way.
Conclusion
That's it! Comments, questions or concerns? Needs more clarity? More pictures? Please post in the thread so that I can improve this tutorial, the code, etc so it is as simple and effective as can be.
Happy cheating! Hopefully this will spare us from hours of gameplay which should be focused on more important things.
