  4. HelloSilicon

    An introduction to ARM64 assembly on Apple Silicon Macs

  5. asm

    Learning assembly for Linux x86_64

    Project mention: Building a Web Server from Scratch (No, Actually) | dev.to | 2026-03-15

    I directly found this guide from Alex Kuleshov, and started reading. That afternoon, I read about 3 posts instead of listening to my teacher, and then went home.

  6. KnightOS

    OS for z80 calculators

    Project mention: UNIX99, a UNIX-like OS for the TI-99/4A | news.ycombinator.com | 2026-02-23

  7. floppybird

    Floppy Bird (OS)

  8. Pure64

    Pure64 is a kernel/software loader for x86-64 systems.

  9. arpilisp

    A Lisp interpreter for Raspberry Pi implemented in a single ARM assembly file

  10. ucity

    The open-source city building game for Game Boy Color.

  11. Cyjon

    A simple, clean code, multi-tasking kernel written in pure Assembly language for 64-bit processors from the AMD64 family.

  12. acheron

    indirect syscalls for AV/EDR evasion in Go assembly (by f1zm0)

  13. fasmg

    flat assembler g - adaptable assembly engine

  14. snake-asm

    Tiny snake game written in x86_64 assembly for Linux

  15. osle

    💾 A tiny and mighty boot sector OS

    Project mention: Show HN: OSle now has a C API and still fits in 510 bytes | news.ycombinator.com | 2026-03-07

  16. 64bit-os-tutorial

    This OS Tutorial expands on the fundamental concepts covered in cfenollosa/os-tutorial and covers entering long mode on the x86_64 architecture. It also uses clang rather than relying on an external crosscompiler. I plan on keeping it up to date, so feel free to submit an issue!

  17. hbc-56

    Homebrew 65C02 computer on a backplane

  18. connectedNES

    📡 A WiFi "modem" that connects your NES to the internet. Includes sample Twitter client.

  19. AssemblyLine

    A C library and binary for generating machine code of x86_64 assembly language and executing on the fly without invoking another compiler, assembler or linker.

  20. mnist-asm-nn

    A complete neural network built entirely in x86 assembly language that learns to recognize handwritten digits from the MNIST dataset. No frameworks, no high-level languages - just pure assembly - ~5.3× faster than NumPy

    Project mention: Mnist neural network implemented in pure x86 assembly from scratch | news.ycombinator.com | 2025-11-02

  21. first_nes

    Create your own games for the Nintendo Entertainment System! This "starter" game is easily extensible for your own projects. Includes references.

  22. supermon64

    Original sources and binaries for Supermon+64 V1.2 by Jim Butterfield

  23. TinyPE-on-Win10

    Smallest (268 bytes) 64-bit Portable Executable (PE) file that displays a message box on Windows 10

  24. hipBLASLt

    [DEPRECATED] Moved to ROCm/rocm-libraries repo
