How to Make your own Cheat Codes

[Hackwiz]

Okay, that rules out everything external, we have exact copies of the game.
I'm thinking you may have something checked/unchecked in dolphin that is affecting your address offset(s).

Let's try this:
-create a new folder to backup some files into
-Navigate to Documents->Dolphin Emulator->Config
-Copy the contents of the config folder and store in the folder you created.
-Delete all the files and folders in the Config folder
-Close window
-Boot up Dolphin.
-Click on options
-Click on configuration
-In the General tab, make sure the enable cheats box is checked
-You will have to reconfigure your controller. In my case, I use a real Wiimote and nunchuck, all I
had to do was go into the backup folder I created, and copy the WiimoteNew.ini file and replace the one in the
Documents->Dolphin Emulator->Config folder
-Set your path to Mario Sports Mix [RMKE01]
-Boot the game
-Once up and fully running, Pause it and navigate to address 0x816035B0
-What do you see?

Vega, I can do this with 5.0-11380 to get checksums, not sure when and if they didn't have that feature available in previous revisions.

-Start up dolphin
-Right click on the game in the game list
-Click on properties
-Click on verify tab
-Make sure all the calculate boxes are checked
-Click on Verify Integrity
-Let it do its thing
