js-dos VS BrowserFS

Funny timing. I actually just built an in-house server this past Friday to host the original Oregon Trail using js-dos because I don't like poking holes in the content filter for sites like archive.org. I didn't worry too much about copyright, as I assumed it was abandonware at this point.

Thanks glad you liked it! It's actually not a port but is running on DOS via https://js-dos.com/, same as Doom and Jazz Jackrabbit. I actually have my 8 favorite Shareware games on my website which can all be played.

Maybe something like https://js-dos.com/ for dos and https://www.emulatorjs.com/ for old game consoles?

DOS Emulation via js-dos

Adding emulators is something I always wanted to do and I have plans to add more in 2022. For 2021 I was able to add Virtual x86 (.img/.iso), BoxedWine (.exe/.zip), JS-DOS (.exe/.zip) & Ruffle (.swf/.spl). Most of these emulators utilize WebAssembly to run non-JS code.

It can indeed run some real windows programs via BoxedWine. I've set it up so you can double click an .exe and it will automatically try and run it, although typically if it needs support dll's then they are all in a zip. For example the zip file for Notepad++ 32-bit x86 can directly run in BoxedWine. You just drag the zip file on, right click and select run in BoxedWine. It can also run DOS apps/games via JS-DOS and has similar mappings for exe/zip. Both emulators make use of WASM as do several other apps, such as the x86 emulator shown in the demo video. My main "OS" is only JS/HTML/CSS written in TypeScript with React/Styled Components.

I think JupyterLite is using localStorage by default. But there are File System APIs for WASM and some external projects[0], I don't think they're yet integrated.

I started my file system with BrowserFS which allowed me to setup IndexedDb as the main writeable location. When in Firefox Private mode it switches to an in memory file system which does not persist. Using BrowserFS also meant I could open ZIP and ISO files as if they were folders. I create a JSON file on build that has the initial public folder directory structure which is used as the readable portion of the file system via plain HTTP GET requests. I've also added the ability to extract RAR files, although I don't currently have it linked to File Explorer to see it's contents before extracting. I can also make and extract ZIP/ISO via fflate.

Thanks for the interest! To do git I used https://isomorphic-git.org/, the terminal is backed by https://xtermjs.org/ and the file system that it writes to is coming from https://github.com/jvilk/BrowserFS. This is all part of my side project (https://github.com/DustinBrett/daedalOS) to build a web desktop environment.

Thanks, I'm glad to hear you liked it! I am using BrowserFS to create writeable data on IndexedDb.
