Are you unsatisfied with how limited the custom stage builder is in brawl?
Have a great idea but you run out of blocks? Maybe you wish they'd let you put those custom peices a little closer together? Or maybe you created an epic stage, but the game ruined your setup by putting the player spawn points in a stupid location.
Somebody decided to fix these problem!
[Brawl Stage Studio] v0.8.03 Beta - Updated 02/25/09 - Smash World Forums He's created a custom stage builder for brawl that you can run on your computer and place any of the stage peices anywhere you want. Even overlaping eachother. To top it off, you can even make your own icon for the stage that the game will display on the level selection screen.
All you need is an SD card to load them to your Wii. No hacking or homebrew required.
