oboromi

A proof-of-concept Nintendo Switch 2 emulator written in Rust

Very WIP — nothing works yet, don’t expect miracles.

Overview

oboromi is a clean and modular emulator framework targeting the Nintendo Switch 2, written in Rust for maximum maintainability and performance.
Its goal is to simulate the new hardware step-by-step, following real architectural assumptions (when available) and clean software design.

Features (so far)

✅ Memory subsystem: Read/write with bounds checks, 64 MiB placeholder DRAM
✅ CPU core: ARM64 registers, memory-mapped, supports NOP, MOV immediate, ADD and SUB instructions with flag updates
✅ Integration tests: Validates CPU–Memory interaction and instruction execution correctness
🧪 Main test harness in main.rs for step-by-step opcode decoding and execution verification
🧱 Modular architecture: Designed for scalable addition of CPU components and instruction sets

🧪 Try It

git clone https://github.com/nikilites/oboromi
cd oboromi
cargo run

If everything is set up right, you should see:

✅ Memory tests passed  
✅ CPU–Memory integration test passed
