I am curently developing a file system for my OS (D.eSystem) with the version 6.1.0.5. The file system is now not working,but it is in development, you can find D.eSystem 6.1.0.5 here: https://github.com/D-electronics-scratch/all_D.eSystem_versions/releases/tag/v.6.1.0.5
Why are you making your own OS?
Is this a learning exercise or a TempleOS situation?
Because I want to build my own OS,I started with OS simulators on scratch.mit.edu,then I switched to Python simulators and then I swutched to C simulators and then I wanted to start building a real OS.
So, a little bit of both ;)
Down the rabbit hole you go. :D
