BirbOS is a Batch "OS" developed by xandrei, Dukemz and Ad2017.
Visit the Github repository here!
UPDATE: We've got a C++ version now! Click here
Join the official Discord server here! (it's deleted)
To get the batch version you just download the repo and run the "birbtool.cmd" file. Enjoy!
Please note this program is not an actual OS and it can't be booted as a computer OS. It's just for fun. Also, it is currently in beta, so stay with us and maybe give some ideas on our discord server. Thanks!
UPDATE: Samyocord (here) has made BirbOS into a real bootable OS! Check it here.
