Ok, i have two options that you can use to get online with project M.
NOTE: THESE METHODS ONLY WORK WITH PM 3.5
Option 1: You will need the following:
8Gb or more Flash Drive
2gb SD Card- MUST BE 2Gb no higher.
Homebrew Channel
USB Loader
Brawl ISO
Download The Brawl ISO to your Flash Drive. I cant provide the link on This site. Then Download Project M on your SD card. Once you have done all of that, you will need to download a usb loader. Preferably USB loader gx then load up your Brawl ISO, go into Game Load, scroll down until you see private server. Pick Wimmfi.de, after that you are still in the game load option.scroll down to ocarina and press A on it until you see the hooktype VBI then turn ocarina on. Done
Option 2: You Will need the following:
8Gb or more Flash Drive
A Computer
PM ISO
Homebrew Channel
Brawl Iso
Usb Loader
First thing, You should still have the Brawl ISO on your Computer. Download the Project M ISO builder. Once you have that. Put your Brawl ISO in the same folder where you see the.bat file. The rest is pretty straight forward from there. But once you get back to the wii use the same method as in option 1 with USB Loader Gx. Except dont use the ocarina part.
Hope this is understandable.
