    Windows 95 in Electron

    Windows 95 in Electron

    Windows 95 in Electron. Runs on macOS, Linux, and Windows

    windows95 in Electron is a quirky, nostalgia-driven project that ports a complete emulation of Microsoft Windows 95 into a desktop application that runs on modern operating systems like Windows, macOS, and Linux. It essentially wraps an emulator — preconfigured to boot Windows 95 — inside a user-friendly app built with web technologies so developers and hobbyists can explore the look and feel of that classic OS without needing legacy hardware or complicated setup. Users can interact with familiar UI elements like the Start menu, File Explorer, and retro applications in a sandboxed environment that evokes early personal computing. Beyond being a playful trip down memory lane, the project demonstrates how emulation can be packaged using modern frameworks & how legacy operating systems can be encapsulated as distributable desktop experiences. It’s become an example of how software preservation and creative programming can intersect, inspiring others to bring historic systems to life.

    WinDS

    WinDS

    Windows XP reimplemented on Nintendo DS

    WinDS is a Reimplementation of the OS Windows(R) XP(R) on the Platform Nintendo DS. Since i started coding Apps for the NDS, my goal was to write a program, called WinDS, which does (nearly) the same as the real appy by Microsoft. In contrast to other little NDS-Operating Systems, just like Woopsi etc. you can code your own Application in Lua for WinDS: just copy the Code onto the FAT-Disk and execute it from within WinDS! This is what makes WinDS so unique. The New Beta 0.95 is out, it features - 52 Classes that are already available within Lua - 25 different types of user interface classes - 8 different predefined dialogs which makes it the perfect GUI sandbox for DS. PS: More time without update means: next update will have even more improvements, as i am still developing ;)
