Below is an example of a cheat file for the USA version of Mario Kart Wii. Create a new text file using your preferred text editor. Make sure the encoding is set to UTF-8. The filename for the text file will be renamed to the game ID that your game is for. In this example, it will be named RMCE01.txt Game IDs can be found on GameTDB. Make sure the Game ID for your region is correct. Inside of the text file, the game ID will be on line 1, and on line 2 will be the game name. Copy your first code two lines below the game name, making sure the name of the code is displayed first then the strings of hexidecimal below that. Seperate each code with 2 lines of space. Code author is not required, but crediting is always a good idea.
