Run the Roblox Android app on Windows, so games get Roblox's native Luau code generation and run fast even on old PCs with built-in graphics.

Skatestrap is a small ELF loader (loader/) that loads Roblox's x86-64 Android libraries and answers the Android, Java and Linux calls they make with Windows ones, plus a launcher (launcher/) with login, settings, FastFlags, graphics options and auto-update. It opens the normal Roblox app home screen, so you can play any game.

How it works

• loader/: ELF loading and linking, a Linux syscall/libc shim, a minimal JNI, EGL/GLES and Vulkan on Windows, input, files, networking.
• launcher/: WPF app (.NET 9, WPF-UI). Your Roblox login stays on your PC, encrypted with Windows DPAPI, and is only ever sent to roblox.com.
• scripts/: tools to check and stage a Roblox Android release (update_apk.sh) and to regenerate the GL/Vulkan/JNI tables.

No Roblox files are in this repository. The launcher downloads the official Roblox Android app on your own machine and checks it against a pinned hash.

Building

• Loader: LLVM clang for Windows, plus the Khronos headers in ../dl/khronos/include. Run sh loader/build.sh.
• Launcher: .NET 9 SDK. Run dotnet build launcher/Skatestrap.csproj -c Release.

Notes

• This is not an official Roblox client, and Roblox may change or block it at any time.
• It does not touch the Windows Roblox client or its anti-cheat.
