Show HN: RetroTick – Run classic Windows EXEs in the browser

https://retrotick.com/
41•lqs_•2h ago
RetroTick parses PE/NE/MZ binaries, emulates an x86 CPU, and stubs enough Win32/Win16/DOS APIs to run classics like FreeCell, Minesweeper, Solitaire and QBasic, entirely in the browser. Built with Preact + Vite + TypeScript.

Demo: https://retrotick.com

GitHub: https://github.com/lqs/retrotick

This is so cool & I'm really amazed by it but I couldn't help laugh at the readme

Funny time we live in lol

Aww. The FreeCell cheats don't work, except for -1 and -2 :)

This is super cool!

Checkout retrowin32 for something similar but written in Rust and not specifically targeting the web: https://github.com/evmar/retrowin32

Not enough Shell32 to run Winfile or Notepad.

Also the command prompt won't list directories for some reason.

Seems to run a lot faster than the previous proof-of-concept I've found (https://www.boxedwine.org/app). Then again, that website runs an entire Linux VM to support Wine.

Please let me plan Sim Theme Park. I can't seem to run it on Crossover on my mac.

Tried it with REVERSI.EXE from Windows 3.0 from https://winworldpc.com/download/c2bbc28f-177a-c2b2-5311-c3a4... DISK02.IMG

(you have to first uncompress it, for example with 7zip).

    $ sha256sum REVERSI.EXE
    a9e319c8f479d1568beec03858fdbb27c71747b2bbed6cd7c9f5e2daa23b40e9  REVERSI.EXE
Result:

The game starts, it begins rendering the board, but then hangs.

Really doesn't surprise me, to be honest:

so which one, the coding by hand part?

Pretty cool. The pipes program doesn't seem to have color. Thoughts on making programs launch from a URL parameter? IE Launching a screensaver or game?

Funny project...

Tried to run SHELL from QBASIC, but it crashes:

  D:\qbasic.exe has encountered a problem and needs to close.
  
  Reason:  illegal instruction
  Address: 0x00002fee
