BootStrap

Mods & Customization

Personalize your Roblox experience with community-made fonts, cursors, sound packs, and themes. Install directly from Settings → Mods in BootStrap.

How to install mods

  1. Open BootStrap Settings → Mods tab
  2. Pick a category (Fonts, Cursors, Sounds, Themes, Emoji)
  3. Click "Browse…" and select a downloaded mod file (.ttf/.otf for fonts, .cur/.ani for cursors, .ogg/.mp3 for sounds, .xaml for themes)
  4. Launch Roblox — BootStrap applies the mod automatically at launch

You can also drop mod files directly into %LOCALAPPDATA%\BootStrap\Modifications\ — BootStrap watches this folder.

Create your own mods

BootStrap mods are simple file replacements. See the Customization wiki for detailed guides on:

  • Fonts: Replace rbxasset://fonts/families/ JSON + add your .ttf
  • Cursors: Drop .cur or .ani files matching Roblox cursor names
  • Sounds: Replace .ogg files in content/sounds/ (e.g. Jump.ogg, Walk.ogg)
  • Themes: Create a WPF ResourceDictionary XAML file with your color overrides
  • Emoji: Use a custom emoji font (Twemoji, Noto Emoji, etc.) mapped via font family JSON
