    Project mention: Pasta/80 is a simple Pascal cross compiler targeting the Z80 microprocessor | news.ycombinator.com | 2025-10-21

    Writing compilers for old CPUs has some real magic in it. It helps you see how processors really work and brings back the old days when hardware was simple and easy to understand. I miss that time. I once wrote a small C compiler in TypeScript for the Intel 8086 and 8087 ([1]), and I have huge respect for the people who coded for those chips. It’s super hard but also very rewarding.

  9. retrotick

    💾 Run .exe in browser — x86/ARM emulator with reimplemented Win32/WinCE/Win16/DOS APIs in pure TypeScript

    Project mention: Theseus: Translating Win32 to WASM | news.ycombinator.com | 2026-05-27

    There is also Retrotick.

    https://retrotick.com/

    It simulates x86 (win32 and win16) and implements Windows APIs in javascript and renders window frames with DOM and contents with canvas (e.g. GDI translates to browser canvas operations). A lot of programs run already but a lot of APIs are not yet implemented.

    I successfullt spent a few days extending it to run a Click & Create based game from my childhood.

  18. chip8-wasm

    A chip8 emulator in wasm

    Project mention: Show HN: Chip-8 emulator in WebAssembly (JS –> WASM) | news.ycombinator.com | 2025-07-20

    I've been learning more about WebAssembly and a bucket list project I've always wanted to complete was to write an emulator. I chose the chip-8 vm as it's popular as a stepping stone project and pretty straight-forward. Only the display opcodes really gave me some trouble, specific to clipping/wrapping and tracking collisions.

    The demo includes some test roms as well as some roms from various octojams. The source is on GitHub.

    https://github.com/KevinBatdorf/chip8-wasm

    I orchestrated the project with TypeScript as I'm used to it and prefer the DX there, I created wrapper functions around the wasm op codes designed in a way similar to how you would write WebAssembly in wat format. So technically it's generated bytecode.
