I found SSBB Stage Studio, it's really cool~

Well for those who are curious,
here is the download to the program, it's basically self explanitory on how to use it. It has some pieces that were in the beta that you can use, you can set spawnpoints, and you can overlap blocks. After you're done, using an SD card that has Brawl Data in it, save the map in private>wii>app>RSBE>st
If you want to share your stages, go ahead and post them. I wanna make a level in the shape of a blockhead beforehand though.
Sure, you can use Homebrew, but after my older Wii kaboomed for no reason, I don't want to risk it again. This is more safer in my opinion. When the Wii U is out, I'll then decide to install Homebrew because, hey, they're probably not going to update it again.
