Customization & Mods

Last updated August 2026Applies to BootStrap v1.0.0+

Where mods live

All mods are stored in one folder:

%LOCALAPPDATA%\BootStrap\Modifications

You can open it directly from the app via Settings → Mods → Open folder, or paste the path into File Explorer's address bar. Inside, you mirror the parts of Roblox's content folder you want to replace — anything you drop in gets layered over the game at launch.

How applying works

Every time Roblox starts, BootStrap copies your Modifications files on top of a fresh copy of the game's assets before the client loads. The original install is never edited: remove a file from your mods folder (or uninstall BootStrap) and Roblox reverts to completely stock assets on the next launch. This per-launch approach also means game updates can't break your setup.

Custom fonts

To change the font Roblox uses in-game:

1. Find or create a font file (.ttf/.otf) with a name matching one of Roblox's bundled font families.
2. Place it under Modifications\content\fonts.
3. Launch any experience — your font replaces the stock family everywhere text renders.

Keep a backup of which original filename you replaced so you can delete it later if you change your mind.

Cursor presets

Fancy some nostalgia? BootStrap ships with ready-made cursor packs that restore Roblox's classic mouse pointers from different eras:

• 2006 cursors — the original chunky pointers from Roblox's earliest days.
• 2013 cursors — the sleeker set many players grew up with.

Pick them under Settings → Mods → Cursor preset; they apply at your next launch. You can still add your own custom cursor images by placing them in Modifications\content\uis\cursors manually.

Sound presets

The same idea applies to audio: built-in sound presets swap Roblox's UI sounds for classic packs — old button clicks, the vintage death sound and other beloved relics. Enable them from Settings → Mods → Sound preset, or roll your own by replacing files under Modifications\content\sounds with any .ogg/.mp3 files using the original names.

Emoji fonts

By default Roblox's bundled fonts don't include emoji glyphs, so emoji render as boxes in chat and billboards. BootStrap includes an emoji-font option that layers an emoji-capable font into the game's font set, letting colour emoji display correctly everywhere. Toggle it once in Settings and forget about it.

Loading custom themes

Your Modifications folder is also where custom interface themes get picked up: drop a valid theme .xaml file in there and it appears alongside the built-in options under Settings → Appearance, ready to activate. Themes restyle the BootStrap window itself rather than the game — read the Custom Themes guide to make your own.
