Hello, i just finished installing windows 10 on raspberry pi4. It works pretty good and runs MP natively. Best of all it supports hid joysticks for anyone interested.
Just go to https://discord.com/channels/711407999503302696/742586223247360121 and download the image on the downloads section and write it with balena etcher on an sd card.
At the moment the latest image supports up to 3 gb of ram and wifi&bt do not work.
Usb and ethernet do work.
