Description
I noticed that Fabrice Bellard added x86_64 support to JSLinux, and I decided to do some work getting TempleOS up and running on it. Enjoy the fruits of my labor: TempleOS, running locally in your browser, completely unoptimized, with some convenient tools for debugging and playing around.

Could you build this?
No Porting an esoteric operating system (TempleOS) to run in-browser on JSLinux requires deep systems programming, x86_64 architecture knowledge, and emulator/hypervisor internals.
What it would actually take: This project requires expertise in x86_64 virtualization/emulation (like Fabrice Bellard's JSLinux or QEMU ported to WebAssembly), custom OS bootloaders, and PC hardware emulation (PIT, PIC, VGA graphics modes). The developer had to debug TempleOS's custom HolyC kernel, BIOS/UEFI boot sequence, and ring-0 memory management under JSLinux's JS/Wasm CPU core. Vibe coding cannot navigate non-standard OS kernel internals, low-level CPU interrupt emulation, or hypervisor debugging.
