Patches src/ide.js before building: restores the dual master+slave writes for ATA Command Block registers (Features, Sector Count, LBA Low/Mid/High) that 1b90d2e7 changed to current_interface-only. Those registers are channel-shared per ATA spec; Win95's ESDI_506.PDR writes them then switches drive-select expecting the values to persist. Found via JS-only bisect. Boots fresh in ~32s with the same sporadic-bluescreen rate as the prod build. The new build has the tcp-connection bus event so SMB uses the clean path instead of the connection-theft hack (guard added for the old-API monkeypatch to skip if the bus handler already accepted). tools/update-v86.js applies the source patch automatically. v86 checkout left clean (patch stashed).

This is Windows 95, running in an Electron app. Yes, it's the full thing. I'm sorry.

Does it work?
Yes! Quite well, actually - on macOS, Windows, and Linux. Bear in mind that this is written entirely in JavaScript, so please adjust your expectations.
Should this have been a native app?
Absolutely.
Does it run Doom (or my other favorite game)?
You'll likely be better off with an actual virtualization app, but the short answer is yes. In fact, a few games are already preinstalled - and more can be found on the Internet, for instance at archive.org. Thanks to @DisplacedGamers I can recommend that you switch to a resolution of 640x480 @ 256 colors before starting DOS games - just like in the good ol' days.

Before you can run this from source, you'll need the disk image. It's not part of the
repository, but you can grab it using the Show Disk Image button from the packaged
release, which does include the disk image. You can find that button in the
Modify C: Drive section.
Unpack the images folder into the src folder, creating this layout:
- /images/windows95.img
- /images/default-state.bin
- /assets/...
- /bios/...
- /docs/...
Once you've done so, run npm install and npm start to run your local build.
If you want to tinker with the image or make a new one, check out the QEMU docs.
