3DS:Custom themes/creation

From Hacks Guide Wiki
< 3DS:Custom themesThis is the approved revision of this page, as well as being the most recent.

Creating custom themes can be done in a number of ways using different tools such as Kame Editor. To use these utilities, you need to have CFW, a custom theme manager (e.g Anemone3DS) and a device that can manipulate files on a SD card.

Theme Editors

Should I use the other editors?

You're free to choose which editor you'll work with, but Kame-Editor is the most user-friendly, which means it has an easy-to-understand interface that'll allow you to make themes with more ease compared to Usagi3DS or YATA+.

Another thing to keep in mind is that Usagi3DS and YATA+ are very outdated. Kame-Editor continues to receive fairly regular updates, hence why you should use it instead of the other theme editors.


What You Need to Know

  1. Take note of the gap size. Each 3DS has a gap size between each screen, and that gap size is a different size for every 3DS model. Commonly used gap sizes are 50, 56, and 68 pixels. If you want to use a full image for both screens, the gap size is very important.
  2. Background music for the theme, the bgm.bcstm, must not surpass 3371008 bytes in size, or the theme may not appear in your custom theme manager or may not play music. Always check the size in bytes, not in MB, because it's possible to have a bgm.bcstm be under the size of 3.3MB like several theme guides recommend, but be more than the limit of 3371008 bytes.
  3. SFX (sound effects) for the theme must not surpass 182KB in size. Be sure to use SFX that are small so that you can include all the SFX you want to in your theme.
  4. Do not make the background music mono. Even though this saves space, it can break the background music for the theme.
