Dump CIA themes to Amemone themes
Since v2.2.0 you can use Amemone to convert CIA themes to compatible theme formats.
Upon selecting the dump theme option in the extra menu, you'll be able to enter a name, and the theme body_LZ.bin and bgm.bcstm will be stored in the folder /Themes/, along with a dummy SMDH file, meaning the theme will be immediately usable in Anemone.
This allows you to translate CIA themes to Anemone themes and thus manage all your themes in one place.
Create a theme
A theme is composed by several files:
- body_LZ.bin - Contains background images and some theme settings.

How to install Anemone3DS and Custom Theme and Splashes (sthetix)
v2.2.0 Covid Christmas Edition 2020/12/25
- Themes without an SMDH file are now supported again.
- If you install a theme without BGM, and then do a BGM-only install, the BGM flag will be automatically set to ensure your music plays properly.
- You can now dump themes. Upon selecting the dump theme option in the extra menu, you'll be able to enter a name, and the theme body_LZ.bin and bgm.bcstm will be stored in the folder /themes/, along with a dummy SMDH file, meaning the theme will be immediately usable in Anemone. This allows you to translate CIA themes to Anemone themes and thus manage all your themes in one place.
- If you scan a QR code and the file host doesn't have a filename set for some reason, you'll now be able to manually enter the filename you want it to be saved as.
- A variety of QR code bugfixes should help the QR reader be more stable than ever™️.
- Various bugfixes and refactoring in the networking code to prevent possible crashes.
- Memory leak fix in theme loading code to allow you to load even more themes.
- Certain previews used to have inverted colors when loaded. This has been fixed.
- ThemePlaza url has been updated to the new one. While this wasn't a problem yet, as the old domain redirects to the new domain, it will prevent issues in the future.
- Various other null dereferences cleaned up to prevent crashes.
v2.1.0 Revival Edition 2020/06/14
- NOTE: This release removes support for themes which don't use an info.smdh file. Most themes use this file, including all themes from ThemePlaza, so it is not expected to be an issue - the changes can be reverted if it caused any issues, but note that themes without an info.smdh are prone to cause crashes.
- Changed Title ID to not conflict with a game - this means you'll have to uninstall the old version of Anemone3DS after updating to v2.1.0.
- Fixed various bugs caused by an outdated libarchive version.
- Fixed various bugs related to previous caused by lodepng by switching to libpng.
- Fixed race condition in icon scrolling.
- Fixed screen tearing in the QR reader.
- Fixed bug caused by playing music even when there was no theme preview.
- Fixed it being possible to try to preview themes/splashes even when there were no themes or splashes.
- Fixed bug caused by attempting to play audio when dspfirm wasn't dumped.
- Fixed bug caused by attempting to install BGM for shuffle themes even when there was none.
- Fixed various bugs caused by not properly zeroing out files when creating them.
- Properly update the installed splash.
- Fixed bug with QR initialization on o3ds/o2ds/n2dsxl. May still not be perfect, unable to test on o2ds, but should be much improved based on reports from testers. Bug reports welcome.
- Updated to newest libctru version & GCC version.
- Patched memory leak in the preview code.
- Updated to quirc v1.1, patching a segfault in the QR code reader.
- Fix multiple race conditions involving the QR code reader which could potentially cause a crash when exiting camera mode.
- Fix crash caused by quirc overflowing the 3DS stack when attempting to scan QR code like images that weren't actually QR codes (such as mechanical keyboards).
- Fix double free which could potentially cause crashes when downloading from invalid zip files.
- Fix QR download from sites other than ThemePlaza which used a different format for content disposition header.
- Fix crashes caused by attempting to load invalid themes.
- Fix memory leak in zip reading code.
- Reset cursor when switching pages of the ThemePlaza browser to fix bug causing corruption.
- Huge improvements to the QR code reader's speed. This is likely the fastest/smoothest it can possibly be (it's now on-par with QRaken and FBI) thanks to a combination of improved multithreading and switching graphics libraries.
- Speaking of switching graphics libraries, we've completely switched from pp2d to citro2d. This allowed us to get the QR code reader substantially faster, as well as guarantees full support for the library in the future. Huge thanks to LiquidFenrir for doing most of the work of the change.
- Switch to using spritesheets to load the sprites rather than just loading them all into the romfs.
- Don't wait for audio to finish loading before displaying the preview image, making previews display in the snappy fashion they used to before the audio player.
- Improved banner quality. Thanks to @TurdPooCharger for this.
