Some Brawl Hacking Sites

http://www.stacksmash.com/ - The first Super Smash Bros. Brawl hacking site I found, and possibly one of the most known.

http://www.kittycorp.freecp.net/ - The other hacking site that came after Stack Smash, THE MOST BIGGEST SITE I KNOW.

http://www.elitesmashhackers.com/ - A smaller site.

That's all for now. Oh, and by the way, here's a preview of what you can find!:

It's the Mr. L Theme. If you're a fan of Mr. L, and don't know what this is, YOU SUCK.
