How to edit the galaxies I make?

[ACIDULATED]

So far, the guide tells you how to make new Galaxies, but not edit the levels in them. How do I do that?

[SuperHackio]

To edit the galaxies, you will need a level editor.

Please refer to the SMG Hacking Wiki, Luma's Workshop for more information on level editing software.

There isn't a full ObjectData folder in the patch, which is necessary to edit levels, so do I copy one over? Also, do I put the stages in StageData?

[SuperHackio]

If you need a full ObjectData, and don't have one already, you should rip one. See Dolphin's Ripping guide for instructions on how to do that.

As for the content that's supposed to go inside StageData, you don't need to copy the base game stages into StageData.

You should follow the Creating a New Galaxy guide to create your own galaxy.
