loongue
Loongue is a monolithic LoongArch LA64 emulator in C focused on deterministic CPU behavior and practical Linux user-mode execution. It is positioned as the smallest actively developed LA64 emulator available today.
Systems developer. Deterministic behavior. Practical execution.
Low-level work, built to run.
I’m David Frogmen, also known as Coops. I build systems-focused software and care about correctness, performance, and making machines do what they are told.

About
Short and specific
I’m a 23-year-old developer with a CS background. I prefer projects where correctness matters and behavior is measurable: instruction semantics, deterministic execution, and practical runtime behavior.
I build things that can run real software instead of living forever as demos.

Interests
CPU emulation, Linux user-mode execution, low-level runtime behavior, and maintainable systems tooling. I like problems where the solution is understanding the model and implementing it correctly.

Current public work
Summary
The goal is a practical LA64 emulator with deterministic behavior that can execute Linux user-mode workloads without turning the codebase into a framework museum. Small, focused, and actively developed.
