This should restore the display from the garbled mess you see and allow you to access the Command Prompt. Press Alt-Enter again to leave Full Screen and go back to Window Mode. (Thanks to @DisplacedGamers for that wisdom) ## Windows 95 is stuck in a bad state On the app's home screen, select "Settings" in the lower menu. Then, delete your machine's state before starting it again - this time hopefully without issues. ================================================ FILE: LICENSE.md ================================================ Copyright 2019 Felix Rieseberg Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

## 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](https://www.archive.org). [Thanks to @DisplacedGamers](https://youtu.be/xDXqmdFxofM) I can recommend that you switch to a resolution of 640x480 @ 256 colors before starting DOS games - just like in the good ol' days. ## Credits 99% of the work was done over at [v86](https://github.com/copy/v86/) by Copy aka Fabian Hemmer and his contributors. ## Contributing 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](./docs/qemu.md). ## Other Questions * [MS-DOS seems to brick the screen](./HELP.md#ms-dos-seems-to-brick-the-screen) * [Windows 95 is stuck in a bad state](./HELP.md#windows-95-is-stuck-in-a-bad-state) * [I want to install additional apps or games](./HELP.md#i-want-to-install-additional-apps-or-games) * [Running in Docker](./docs/docker-instructions.md) * [Running in an online VM with Kubernetes and Gitpod](./docs/docker-kubernetes-gitpod.md) ## License This project is provided for educational purposes only.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. ================================================ FILE: docs/docker-instructions.md ================================================ # Running windows95 in Docker ## Display using a volume mount of the host X11 Unix Socket (Linux Only): **Requirements:** * Linux OS with a running X-Server Display * [Docker](http://docker.io) docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY --device /dev/snd --name windows95 toolboc/windows95 Note: You may need to run `xhost +` on your system to allow connections to the X server running on the host. ## Display using Xming X11 Server over tcp Socket (Windows and beyond): **Requirements:** * [Xming](https://sourceforge.net/projects/xming/) * [Docker](http://docker.io) 1.

    windows95 Apps & Games

    I've installed a few apps and games for you to try out. Check out the Games folder on the desktop!

    If you want to try other games, I recommend trying to find them on the Internet Archive. On your host computer, visit https://archive.org, then find the "Classic PC Games" category. Once downloaded, you can import them into windows95 from your host's Download folder.

    Emulation Engine

    None of this would be possible without the people working on v86, in particular Fabian Hemmer aka copy. You can visit his website at copy.sh. It also wouldn't be possible without the QEMU project. If you enjoy running old systems, you probably want QEMU - windows95 is merely a toy, QEMU lets you actually run old systems in a stable manner.

    Electron

    Electron is a framework for building desktop applications using web technologies. It's what powers windows95. You can visit the project's website at electronjs.org (in a modern browser, not in windows95).

    MS-DOS Display Issues

    If MS-DOS seems to mess up the screen:

    1. Hit Alt + Enter to make the command screen "Full Screen" (as far as Windows 95 is concerned)
    2. This should restore the display from the garbled mess you see and allow you to access the Command Prompt
    3. Press Alt-Enter again to leave Full Screen and go back to Window Mode

    (Thanks to @DisplacedGamers for that wisdom)

    windows95 Stuck in Bad State

    If windows95 becomes unresponsive or stuck:

    1. On the app's home screen, select "Settings" in the lower menu
    2. Delete your machine's state before starting it again
    3. This should resolve the issue when you restart

    Welcome to Windows 95!

    Hi, I'm Felix, the maker behind windows95. I hope you're having fun!

    Reach out to me in a modern browser (as in: not in windows95) on felixrieseberg.com or find me on Bluesky at @felixrieseberg.

    The Internet!

    In a major update since the last version, windows95 now has working Internet! That said, most modern websites will not work, so brace yourself. I recommend using The Old Net to travel back in time.
