Please follow the instructions below. Note: The instructions are for the Hackless method. If you're using a Homebrew method, simply delete any previous version of Project M, extract the files to your SD card then boot Homebrew and select Gecko OS. If you are using the Installer, you will prompted to select a package to download.
- Delete any custom Brawl stage files on your Wii and SD Card! Don't assume that because you haven't made any there aren't any; 3 custom stages are included with a new savefile of Brawl.
- Delete any previous version of Project M from your SD Card and make sure the card itself is not named "Project M" or any derivative thereof.
- Unzip the file and open the folder that comes out, or use the Installer to download and generate the folder instead.
- Move the contents of that folder to your SD Card.
- Boot up Brawl and go to the Stage Builder.
- Gecko OS will launch; select Launch Game.
- You will see a straploader saying Project M 3.5. Additionally, if your menu image looks like the image below, then go ahead and play and enjoy Project M!
