Pi Lab has created the ultimate nostalgic version of Raspbian for the Raspberry Pi 4 single board computer, with their releases of Raspbian XP and Raspbian 95. By making a custom theme for each operating system, to have the Pi 4 boot up to the Windows chime, with the same (or at least very similar) look and feel of one of these very popular operating systems. It also includes and ton of retro gaming emulators that are pre-configured and the Box86 emulator which can run your favourite old school Windows games and apps and even can emulate Windows 98 inside Raspbian.
It’s still very much a work in progress with updates being shared regularly along with update tools inside the operating system.
It’s worth noting that it runs by default in an overclocked state so make sure your Pi 4 has some active cooling since it will be running hotter than normal.
To install this on your Raspberry Pi 4, you’ll need to download one of the images that are linked in the video description and then ‘burn’ that image to an appropriate sized microSD card for your Pi (I used a 32gb card) using a tool like the Raspberry Imager Tool (available for Windows/Mac/Linux). Insert the microSD card to the Pi and let it boot twice while it arranges things then you’re good to go!
Keep an eye on Pi Lab YouTube channel for more updates and improvements as they seem to have daily upgrades and tweaks to the system.
