I felt that while great applications, the current alternatives were a bit lacking in the Preview and User Experience Department.
So, another alternative for Custom Theme Creators, hopefully easing the process of creating them:
Usagi 3DS Theme Editor:
Requires: .Net Framework 4.5 Windows Operating System (WPF doesn't work under Mono! However there are some markup languages which do, you can try to fork and port it)
Features: Live (Animated) Preview: supporting all Render Modes and Frame Types for both Screens Colored and Textured Application/Folder Icons on the Preview Animated Cursor on the Preview Image Palette: pick colors from up to 20 colors from the top and bottom images most used colors BGM Preview: Preview only, to generate the BGM.BCSTM, you may use the YATA+ Converter or similar alongside this application Image Dithering: I hate banding, and i bet will now too: Example Available in the following languages English Brazilian Portuguese Spanish - by @dsoldier Italian - by @RayFirefist French - by @Kerouz
The Library (ThemeEditor.Common):
Requires: .Net Framework 4.5
Built from the Ground Up in a Object Oriented manner, you may use this for your own projects that require Loading/Editing the Theme files, without rewriting the wheel
Special Thanks to YATA, pk3DS and DSDecmp, from where the LZ11 Decompressing and Texture Decoding Algorithms were taken/ported from
