Hope you plan on dealing with using ****-tier tools, in that case. Why have the simplicity of Brawl Stage Manager's drag-and-drop functionality when you can overwhelm and frustrate yourself with the messy interface of Brawl Box? After all, rifling through file after file with a thousand components in a thousand places has a certain headache-inducing charm that Brawl Stage Manager's all-in-one interface just
lacks.
Just get Brawl Stage Manager. It's easier. You just drag and drop, for
everything; .PACs, .RELs, stage previews, stage icons and names, even
music and the title for those tracks.
If you're that new to modding your PM build, then you should be warned that Brawl Box (at least where stage/BRSTM/costume management is concerned) is a frustrating tool to have to use, not to mention that editing just one stage is a mundane and time-consuming task. Using the Brawl Stage and Costume Manager tools will make everything faster and easier.
Seriously, doesn't this look
so much better than Brawl Box?
Want to open a new stage up? Just click it in the left-hand pane. Need to replace Battlefield with a different stage? Drag the .PAC for the new stage into the center preview. Is there a .REL required? Drag and drop into the stage data in the top-center above the center preview. Are you needing to update the stage portraits? Just drag and drop the pictures onto the previews. Stage title? Drag and drop, or 'generate name' with your own font and size settings. Emblems? Drag and drop, or modify through the PAT0 maps.
BRSTMs? Again, just drag and drop into the center-bottom area specialized for them, and even rename them.
**** Brawl Box.
