SM64DS Editor (SM64DSe) is a SM64DS level editor originally made by StapleButter, with many extra features added by Fiachra, like model importing and exporting.
SM64DSe lets you edit levels by dragging objects within a 3D render of the level. You can add and remove any kind of objects: coins, powerups, enemies, paths, warps...
It is also possible to replace models of levels or objects, with completely new models, or to just edit their textures.

Whitehole is a SMG1/2 level editor made by StapleButter, with help from Dirbaio, Ninjifox and others.
Whitehole currently supports editing whole galaxies or individual zones, and editing current objects as well as adding or removing objects. It also has a built-in BCSV editor that will let experienced users do whatever they want.
It also has an important feature, which makes it much easier to use than Anarchy in the Galaxy
: it can render galaxies and zones like they look ingame, and even let you interact with the rendering and move objects without caring about their coordinates.
However Whitehole currently doesn't support as many object types as Anarchy in the Galaxy, but this will be improved in the next releases.
SMG editing may seem complicated at first glance, however we hope that Whitehole will be intuitive enough for you. If you have trouble with it, don't hesitate, ask us for help on the forums or the IRC.
