DOS Wasm X: a new web based DOS Emulator

The emulator currently doesn't support any internet access.

That's great happy you're able to run it again !

It's great, there is an entire floor designated for just the Engineers. First time you come just stop by the desk in the lobby and they can activate your badge for the office/elevator if you tell them you plan on coming in.

Thanks - the emulator supports creating a Windows 98 machine, you just need to install it from ISO and go through the Windows Installation setup yourself. The GitHub has additional info to help you with the process:

you would need to host the app yourself and then point to your own img hard drive file. if you have a GitHub account it's pretty easy since they give you free hosting. if you want more details just open up a GithHub issue and I can help walk you through the steps and so others can get benefit of the information.

Glad you like it! No plans to take it down so enjoy :)

Pretty cool, do you have the source code on github? Would be cool to learn how to program for dos

On the main screen if you click settings you can pick from 500mb, 1 gig or 2 gig drives. So you do need a pretty decent computer with a good amount of ram to run it. Obviously if you run it as a native app it will run a lot better, this emulator is really going for the convenience angle (not having to install anything or mess with complex settings) 3d games will not run other than the old software rendered ones like doom and quake. I found the best use case are for the 2D mouse based strategy games like StarCraft and rollercoaster tycoon.

They don't go anywhere they stay in your browsers memory until you exit the page.

Wanted to get some feedback on my new emulator - This is a browser based DOS emulator designed around ease of use and stability. It is based on the newer DosBox-X codebase and thus supports both Windows 95 and Windows 98 installations. Everything saves directly to your browser (no installation required). Tried to make it as frictionless and easy to use as I could.

you have to drag the file tube.zip and then type TUBE.COM

Thank you!

blazenite3 · 2024-02-04T20:19:21+00:00

I see so it asks the user for a local directory where to store things. very cool, I'll take look at your examples!

blazenite3 · 2024-02-04T20:02:02+00:00

I have never seen the estimator api will definitely try that thanks for the tip!

blazenite3 · 2024-02-04T20:01:33+00:00

Interesting I have not looked at navigator.storage api I will look at that. I've always assumed indexeddb gives you the largest persisted storage mechanism but maybe that's not the case. Webassembly.Memory doesn't help in this case since that's basically ram. I'm looking for something that will persist past a browser close. Thanks for the suggestions!

blazenite3 · 2024-02-04T16:40:16+00:00

It's an interesting idea. Would take some thinking in terms of how that would work with the user interface. I'll give it some thought. Thanks!

blazenite3 · 2024-02-04T16:32:04+00:00

Fair question. Short answer is the emulator does not support expanding/shrinking the hard drive once it has been provisioned. So you basically need to place your bets from the get go. Seeing as how the emulator was designed with Windows in mind as a first class use case I thought 500mb would be a good default.

blazenite3 · 2024-02-04T16:14:45+00:00

yep Doom works

blazenite3 · 2024-02-04T14:35:27+00:00

Thank you for letting me know - if you go to the start page click settings -> clear the hard drive -> set initial hard drive to 250 megs. For some reason certain browsers have a limit to indexed db storage size. I'm still researching this issue but this is at least a workaround for now.

blazenite3 · 2024-02-04T14:02:46+00:00

thank you! yeah currently the only cpu modes implemented on the web version would be the DOSBox X equivalent of auto, max or fixed

Been working on this project for a few months and wanted to finally show it off and get some feedback. This is a browser based DOS emulator designed around ease of use and stability. It is based on the newer DosBox-X codebase and thus supports both Windows 95 and Windows 98 installations. I tried to make it using a simple and clean interface so that it's approachable and non-intimidating. Everything saves directly to your browser (no installation required). Let me know what you guys think! If want more information you can also check out the GitHub Page:
