TerraInveditThreedee is an editor for terraria.

There are versions .3dsx and .cia
Like Terraria editor, I think it's possible to have PCHex++ or PHBank in .cia
(I just think)
What I wanted was that the PCHex++ and PHBank had a GUI. And they have! I'm glad to see the two homebrews that I like so much, receiving updates that we ask to Slashcash and Gocario.
Of course, they do it without asking anything in return. And I admire them, by knowledge and interest to make homebrews so good!
Now that many people have access to CFW, many people will ask for .cia version. (me too) But for now, I'm happy with .3dsx version.
