DOS Wasm X is a fully functional DOS emulator that runs entirely in your web browser. Powered by DOSBox-X compiled to WebAssembly, it provides a complete x86 DOS environment for running classic games, applications, and even Windows 95/98 — no downloads or plugins required.
This version is my attempt to get it to run on mobile but implementing the mobile keyboard as input. This saves having to rely on the clunky inbuilt virtual keyboard.
I have had mixed results but you are free to try it.
I did not write DosboxX and take no credit for it. I just added the mobile keyboard overlay.
You can find full details of DosboxX at is website dosbox-x.com
