For USB Loader users: Use CFG Loader. Even the official Brawl Minus team says it is the only working loader. I say it too.
Anyway, put the codes on either your SD or USB, wherever it looks for codes (probably in the loader's base folder, like X:\usb-loader\codes\); put the "private" folder on your SD, non-negotiable.
For Disc users: do the same as above, except every file must be on the SD, excluding GeckoOS.
For Dolphin users: if you have a Wii, use the Disc setup method, then use the Homebrew Browser to grab the SD Dumper. You must have at least 50% of your SD free to do this!
When the dumper makes the .RAW, go into Dolphin/User/Wii and move it there as SD.RAW.
Then get the GeckoOS DOL/ELF and launch it from Dolphin. Set the default ISO to Brawl or change the virtual DVD to Brawl, and there you go!
Alternatively, if your SD does not have 50% free or if you do not have a Wii, plug your SD into a PC some way, then use WinImage (even the trial version) to make a .RAW of your SD. This will be faster than the other way, but if you don't like bloatware, you can use Option A.
