Native Legacy

a backwards compatibility layer for Roblox that allows people to play their old favourite games again!

---

What?

Native Legacy restores dated engine behaivour on the modern Roblox client, by modifying scripts and creating a sandbox.

Examples of things NL does:

• Loads a giant library of uncopylocked & archived games.
• Grants access to some VIP rooms and admin features through Badge/Friend spoofing.
• Restores Flag/FlagStand functionality.
• Fixes HopperBins, and restores server-sided mouse access.
• Emulates the Sets API.
• Redirects InsertService calls to AssetService.
• Provides a pseudo version of BadgeService.
• Restores popular linked sources to fix Brickbattle tools.

What Makes it Work?

The scripts inside of games/models have an injector appended to the top of them. Example below.

Before:

local MOUSE_ICON = 'rbxasset://textures/GunCursor.png'
local RELOADING_ICON = 'rbxasset://textures/GunWaitCursor.png'

After:

require(game:WaitForChild("native_legacy"))(getfenv());local MOUSE_ICON = __STRDEC 'rbxasset://textures/GunCursor.png'
local RELOADING_ICON = __STRDEC 'rbxasset://textures/GunWaitCursor.png'

The loader underneath game forces the environment into the sandbox, allowing Native Legacy to alter the script's behaviour through patches.

If you've ever played Script Builder games, they generally function similarly - accept our primary case is for compatibility rather than restrictions.

Licensing & Contributions

Native Legacy is currently provided in a source public state - this means all rights are reserved and the project is not technically open source. This will change once we reach our MVP - please stay tuned!
