How can I install Project M on my Wii U without SSBB?

[CardinalCyn]

After years of use, my Super Smash Bros. Brawl disc has finally broken from use. It's incredibly scratched, so it won't even load as a disc. Right now, I'd like to play Project M without necessarily using SSBB to get into the load out. As for information about my console, I use a Wii U. I have a homebrewed Wii, and I am currently ordering a Mayflash Adapter so I can use my gamecube controllers on it. So firstly, how can I play Project M without using my SSBB? And also, will my adapter work on PM and maybe Melee? It's a mayflash adapter with 4 ports. Thanks in advance.

Use a USB loader and an ISO of Brawl/PM (please don't ask where to get the ISO on here). You'll need to install cIOSes, if you haven't done so already.

The adapter may be compatible with Melee (google to see if there's a Nintendont setup file for it), but is not compatible with Wii games (including Brawl/PM).
