"I installed Windows 95 in DOSBox using this guide from a virtualised CD, then packaged up the disk image, along with an AUTOEXEC.BAT file and a custom dosbox.conf using Em-DOSBox," Faulds writes.

Leveraging Emscripten and DOSBox, the browser-based version of the operating system was built by student Andrea Faulds, who was born a year before Windows 95.

Faulds says that this impressive feat was achieved by installing Windows 95 OSR2 in DOSBox, then packaging up the disk image, along with an Autoexec.bat file and a custom dosbox.conf using Em-DOSBox.

Here it is running the bootup sequence: To work this magic, shutterbug2000 used a variant of DOSbox, an open-source DOS emulator, a Windows 95 .img file, and a “new” Nintendo 3DS.

Apparently, the creation process involved installing Windows 95 OSR2 in DOSBox and packaging the disk image along a custom dosbox.conf and an Autoexec.bat file.
