Change Region of Game Save? (Mario Kart Wii)

[puter41]

I have been seriously grinding out Mario Kart Wii recently, and I was using a PAL version. For reasons I just won't get into, I need to use an NCSC-U version of the game now.

I searched the web as much as I could for solutions. I found a bunch of stuff for other games, but not for Mario Kart Wii. The closest I got was this thread where the guy quotes someone saying that the method should work for anything, but it doesn't seem like he knows what he's talking about (NOT THAT I DO I'm no better lol) because the whole tutorial just didn't match my save file.

I'm prepared to edit binary files or use small programs, but don't really want to buy any kind of software. I grinded for a really long time on the PAL version, and if I'm being honest I really don't want to do all of that again. And I have low hopes that I'll actually get a solution, but I might as well ask!

Also, if for some crazy reason you can't tell me how to do it and would have to do it yourself, or if you just want to test with it, I'll include my PAL save as well as a clean PAL and NTSC save. I would really prefer to do it myself though, just so I could do it again if I ever needed to.

(I wasn't 100% sure how to categorize my problem so feel free to change which form this thread should go in.)

To see where your save file is stored, you Right Click your Game, Click Properties -> Info Tab, Game ID, the first eight numbers is the first folder name and the last eight numbers is the second folder. The folder I'm referring to are in Dolphin Emulator\Wii\title\first set of 8\last set of 8.
After this go into the data folder and copy the contents of the folder, head over to the new region game, do the exact same thing but paste the contents in the data folder instead of copying them. 

You are now able to use your old save files in any region based game.
NOTE, this is not permanently, disabling the gecko codes will give you a screen that says to create new save data.
