Getting Started (themes) - Universal-Team/pkmn-chest GitHub Wiki

Things you'll need:

Editing colors:

• Text editor

Editing graphics:

• GIMP (or other program capable of saving 16-color index .bmp files)
• g++ (c++ compiler, for my bmp2ds image converter)
  • On macOS or Linux you probably either already have this or can get it by installing developer tools or from your package manager or so
  • On Windows installing Ubuntu for the Windows Subsystem for Linux comes with this, I'm not sure if its possible to run compile my bmp2ds conversion tool on windows native

Editing music / SFX:

• mmutil (maxmod util)

Basic steps:

1. First you'll need to create a folder for your theme in sd:/_nds/pkmn-chest/themes/, for more info on what goes where in the theme folder see the Theme folder page.
2. In that folder you'll need a theme.json if you want to edit any of the text or solid color draw colors.
3. If you want to change any graphics see the editing graphics page.
4. If you want to add custom music or sound effects, see the custom music page.
