coercing/roblox-external-source — reverse-engineered prompt

I found this old C++ Roblox external source and I want you to turn it into something safe and usable as a learning project instead of a cheat. Please get it building cleanly in Visual Studio, fix the broken parts the README hints at, and strip out anything meant for bypassing protections, drivers, anti VM stuff, or game exploitation.

What I do want is a harmless desktop demo that keeps the general structure, loads and saves its settings as JSON in LocalAppData, has a simple overlay style window that can render ESP like boxes on fake sample data, and shows how the config, rendering, and app flow work in a clean way. If there is auth code or old protection code, either remove it or stub it out so the project still runs.

Please clean up obvious paste code issues, comment the important parts, and leave me with something I can open, build, and run locally. If you need to, look up current docs online.
